Sodium Tartrate

Chemical ID: CAS Formula HS Code Database

Product Identification: Sodium Tartrate

Property	Manufacturer Commentary
Product Name & IUPAC Name	Product is typically referred to as Sodium Tartrate in trade and technical contexts. IUPAC naming follows: Disodium (2R,3R)-2,3-dihydroxybutanedioate. There is a need to confirm the correct stereochemistry is sourced or specified, as both d- and dl- forms are encountered, and many applications (including food/pharma) require explicit declaration.
Chemical Formula	The stoichiometric formula is Na2C4H4O6 • 2H2O for sodium tartrate dihydrate. From a process perspective, the water of hydration is commonly analyzed batch-wise, as ambient humidity and dehydration risk affect specification — especially in warmer or lower-humidity storage conditions. Hydrate state must align with downstream processing requirements.
Synonyms & Trade Names	Commercial users and technical buyers frequently encounter these alternative designations: Rochelle Salt (though strictly for the potassium sodium salt), Disodium tartrate, Seignette salt (historically). Appropriate synonym usage in documentation requires manufacturer-side diligence, since some markets and customers expect full IUPAC, others rely on common English or legacy names. Avoiding ambiguity in grade and stereochemistry is essential when reviewing purchase orders.
HS Code & Customs Classification	Typical customs classification for sodium tartrate falls under HS code 29181980 (Salts and esters of tartaric acid, other than potassium sodium tartrate). Region and end-use affect customs documentation; checker teams audit correct assignment depending on anhydrous/dihydrate and salt form. Harmonized System (HS) code classifications periodically update; trade compliance teams review changes to avoid border delays or tariff misapplication.

Sodium Tartrate: Technical Properties, Manufacturing Process & Safety Guidelines

Physical & Chemical Properties

Physical State & Appearance

Sodium tartrate is supplied as a crystalline powder or granule. Most batches carry a white to off-white color, which varies slightly depending on hydration state and trace impurities originating from raw materials or process water. The substance is essentially odorless. Melting point varies by hydration; the anhydrous form decomposes at elevated temperatures before reaching a clear melt, while the dihydrate loses water and then decomposes. Boiling and flash points do not provide meaningful industrial parameters due to decomposition occurring prior to vaporization. Bulk and tapped density are influenced by crystal form, granule size, and grade specification, so storage and batching equipment settings rely on batch-specific QC data.

Chemical Stability & Reactivity

Routine production and storage do not yield significant concerns for instability, provided the material stays dry and sealed. In contact with acids or strong oxidizers, the tartrate moiety undergoes breakdown, releasing carbon dioxide or converting to tartronic or oxalic acids. These reactions can accelerate if excessive humidity or elevated temperatures persist, highlighting the importance of strict warehouse environmental controls, especially in humid or tropical regions.

Solubility & Solution Preparation

Sodium tartrate has high solubility in water, with dissolution rates depending on temperature, particle size, and agitation. Solution preparation for downstream or analytical use needs monitoring for undissolved residues, which may indicate batch-specific caking, aging, or contamination. Solution stability is grade-dependent; higher-purity grades provide lower risk of insoluble particles during storage or pH adjustment.

Technical Specifications & Quality Parameters

Heavy Metal Impurities	Process & region-dependent	AAS/ICP-MS

Impurity Profile & Limits

Primary impurity sources stem from raw tartaric acid, caustic sodium reagents, process water, and batch-to-batch variances in crystallization. Heavy metals (Pb, Hg, Cd), organics, and insolubles receive close attention in our QC program, particularly for food or pharma grades. Detailed impurity limits are not universally fixed; rather, they are tailored to end-use requirements and regulatory alignment.

Test Methods & Standards

Release analysis depends on both in-house and customer-specified protocols. Titration confirms assay. ICP or AAS screens for trace metals. Colorimetric, gravimetric, and chromatographic methods handle residual organics. Each batch record documents method versions and instrument calibration.

Preparation Methods & Manufacturing Process

Raw Materials & Sourcing

Tartaric acid—naturally-derived or synthetic—and high-purity sodium carbonate or sodium hydroxide serve as starting points. Sourcing prioritizes consistent origin, regulatory documentation, and impurity fingerprinting, since regional suppliers sometimes introduce unexpected contaminants.

Synthesis Route & Reaction Mechanism

The main synthesis employs neutralization of tartaric acid with sodium carbonate in controlled aqueous solution. Carbon dioxide evolves as a byproduct. Reaction progress hinges on pH, agitation, and temperature; incomplete neutralization leads to acid tartrate forms, which lower product quality. End-point detection ensures batch homogeneity and prevents overdosage of sodium source.

Process Control & Purification

Purity is maintained through multi-step crystallization, repeated filtration, and water washing. Crystallization parameters—temperature ramp, seeding, and evaporation rate—are tuned per batch to avoid inclusion of mother liquor or fine insolubles. Mother liquor recycling and impurity bleed-off are used to improve yield while controlling cumulative impurity build-up across campaigns.

Quality Control & Batch Release

Every batch is registered with in-process checks: pH, solution clarity, weight loss, and post-crystallization inspection for off-spec color, flow, and particle size. Final release hinges on assay, water content, trace impurities, and functional performance when supplied for analytical or critical food/pharma applications.

Chemical Reactions & Modification Potential

Typical Reactions

Sodium tartrate acts as a mild base and a chelating agent owing to its dicarboxylate groups. In oxidation-prone environments, it undergoes gradual decomposition, especially at high temperature. Under acidic conditions, conversion to tartaric acid or mixed acid salts occurs. In presence of strong oxidants, further degradation toward oxalic acid and CO2 is possible.

Reaction Conditions

Process chemists select catalysts, temperature, and solvent conditions according to downstream need. Temperature ramps and reagent choice impact yield and impurity formation. No universal recipe applies; parameters change with customer target and local regulatory compliance.

Derivatives & Downstream Products

Tartaric acid recovery, transition-metal tartrates, and mixed tartrate salts represent common downstream directions. Derivatization depends on purity, hydration state, and absence of interfering ions, so feedstock traceability is crucial.

Storage & Shelf Life

Storage Conditions

Drums and lined bags carry sodium tartrate under dry, cool, and well-ventilated conditions. Product sensitivity to atmospheric moisture means warehouses employ humidity monitoring, especially in coastal regions or summer months. Light exposure does not influence the batch materially. Inert gas blanketing is typically unnecessary for standard grades, though high-purity or analytical grades may require extra protection.

Container Compatibility

Standard packaging employs polyethylene-lined fiber drums or HDPE bags. Extended direct contact with unlined metal or reactive plastics can introduce trace contamination or discoloration, particularly in the presence of residual moisture or volatile process contaminants.

Shelf Life & Degradation Signs

Product shelf life aligns with retained solubility, color, and free-flow properties, each assessed at periodic QC intervals. Caking, yellowing, or appearance of insolubles indicate compromised storage or expiry. Shelf life varies by grade and packaging; exact duration is confirmed by retained specification compliance at retesting.

Safety & Toxicity Profile

GHS Classification

Current global regulatory documentation lists sodium tartrate as having low acute toxicity, though grading may adjust classification based on impurity and application. Non-food grades may hold additional hazards due to contamination. Food and pharmacopeia grades undergo specific hazard reassessment each production campaign.

Hazard & Precautionary Statements

Eye and skin contact may lead to mild irritation in dust-generating applications or during bulk handling. Good industrial hygiene—dust masks, gloves, local exhaust—minimizes personnel exposure, especially for packaging or reconstitution operations. Spillage in damp areas can cause localized slipperiness due to high solubility.

Toxicity Data

Oral toxicity sits in the low hazard band per animal models and historical food additive evaluation. Processing cross-contamination with higher-risk chemicals—relevant for non-food supply chains—represents a greater concern for worker and downstream safety and is addressed during batch segregation and line clearance.

Exposure Limits & Handling

No universally mandated TWA or STEL value applies, though general nuisance dust rules inform workplace exposure assessment. Facility SOPs require personal protective equipment for handling powders. Safety showers and eyewash stations remain standard near handling points.

Supply Capacity & Commercial Terms: Sodium Tartrate

Production Capacity & Availability

Manufacturing sodium tartrate at scale requires reliable access to tartaric acid and sodium carbonate or sodium hydroxide. Production volume can shift based on tartaric acid fermentation yields tied to wine and grape industry cycles, with higher crop years generally resulting in higher output of source material. In practice, daily output is set by available crystallizer capacity and drying equipment throughput, with batch consistency closely monitored for total sodium, tartrate, and moisture content. Capacity expansion hinges more on feedstock procurement and waste stream management than on reaction or crystallization bottlenecks. OEM-grade and food-grade batches are run separately to avoid cross-contamination, with dedicated vessels where customer requirements call for trace contaminant specifications. Short-term spikes in demand may be met by prioritized campaigns but are bounded by tartaric acid availability in the upstream market.

Lead Time & MOQ

For regular customers, lead times are typically dictated by production scheduling, pre-allocation of upstream tartaric acid, and packaging slot availability. Custom or high-purity batches may require additional validation time, primarily for analytical confirmation and process documentation. Minimum order quantities are affected by batch reactor size and packing line economics; region-specific regulatory documentation can also drive up MOQ if new label approvals are needed.

Packaging Options

Standard sodium tartrate is packed in lined woven bags or HDPE drums. High-purity lots for food or pharma are limited to primary PE bags and sealed drums. Anti-static liners or oxygen-barrier films may be specified for electronics or specialty applications. Packaging mode is largely grade- and destination-driven, shaped by customer process handling needs and by transit regulations such as EU and FDA food contact directives.

Shipping & Payment Terms

Bulk freight is dominated by liner vessel shipment or inland bulk truck where volume justifies it. Strict chain-of-custody documentation accompanies each lot, especially for export to the EU or US. Payment terms are typically linked to batch release success and contract compliance, with documentary L/C common in new-market transactions. Late delivery penalties and pre-shipment inspection terms are stipulated on long-term supply contracts to mitigate customer-side process risk.

Pricing Structure & Influencing Factors

Raw Material Cost Composition

The primary cost driver is tartaric acid, representing the bulk of raw cost input. Tartaric acid’s own pricing is sensitive to grape harvest results in Southern Europe and South America—surplus supply can depress costs, while poor vintages tighten the market. Sodium carbonate or hydroxide input fluctuates with energy prices and caustic soda sector operating rates. Crystallization utilities (steam, water, cooling) account for a secondary cost block, affected by site local energy pricing and the effectiveness of heat recovery systems.

Fluctuation Causes

Largest upward price pressure stems from decreased tartaric acid supply in years with weak wine and fruit harvests. Currency volatility—especially against the Euro for EU-origin tartaric acid—also passes directly into cost basis for export contracts. Packaging material costs, especially for food- and pharma-compliant high-barrier liners, typically rise on cycle with global polymer and energy prices.

Graded Price Differences: Core Influences

Price steps between industrial, food, and pharmaceutical grades track with required purity level, trace ion control, and certification costs. Food/pharma grades command premiums due to both batch segregation and additional third-party audits (such as FSSC22000, USP/FCC compliance audits), along with more stringent packaging and documentation. Certification for kosher, halal, or allergen-free status can add both direct and opportunity cost in production and validation. Customers seeking bespoke particle size or very low moisture lots also face higher per-unit cost driven by additional sieving, drying, and analysis.

Industrial Processing/Technical Applications	Technical/Industrial Grade	Process-determined purity, tailored to cost and downstream needs	Focus on price-performance ratio, acceptance of application-tolerable impurities

Key Parameters by Application

• Purity: Most downstream operations specify minimum purity. Food and pharmaceutical requirements typically demand higher purity thresholds and tighter control of heavy metals, chloride, sulfate, and residual organics. Technical and industrial processes may accept broader impurity profiles for cost efficiency.
• Physical Form: Some filling, blending, or dissolution systems require particular crystal sizes, granular flows, or packing densities. Food and pharma usually specify particle size for dosing accuracy or dissolvability; analytics may prefer fine crystalline for rapid dissolution and minimal residue.
• Residual Moisture: Strictly managed for process stability. High moisture may affect shelf life, cause caking in storage, or influence weight-based formulation. Analytical applications demand low moisture to avoid dilution error. Technical grades may not restrict this as sharply.
• Trace Impurities: Iron, heavy metals, and organic byproducts must remain below set limits for food/pharma but may show higher variation in technical uses if downstream processing or product performance tolerates this level.

How to Select the Right Grade

Step 1: Define Application

Clarify the sodium tartrate’s intended end-use process. Food additive lines, medical production, titration laboratories, and chemical manufacturing all drive different technical specifications. Clear definition ensures downstream performance and regulatory fit.

Step 2: Identify Regulatory Requirements

Determine if the application falls under food, pharma, or laboratory regulatory controls. For food additive use, refer to endorsement by FDA (USA), EU, or national food codes. Pharmaceutical manufacturers should consult their relevant pharmacopoeia. Technical and analytical grades must align with customer, internal, or local health and safety rules as applicable.

Step 3: Evaluate Purity Needs

Assess the allowable tolerance for non-tartrate content and physical inconsistencies. High-purity workflows, such as injectable drug precursors or quantitation-grade analytical run setups, require lowest impurity level. In contrast, industrial applications sometimes allow for a broader impurity range if it does not influence the overall process.

Step 4: Consider Volume & Budget

Larger-scale technical operations typically weigh cost considerations against purity requirements. Selectivity in grade choice helps avoid over-specification, minimizing raw material spend without compromising downstream robustness or compliance.

Step 5: Request Sample for Validation

Before full procurement, obtain a sample from the intended grade and process batch. Conduct in-plant validation—test for compatibility, formulation behavior, and any unanticipated side-effects in target conditions. Manufacturer sample release follows internal batch control and must meet specification as agreed per customer’s documented end-use requirements.

Manufacturer Quality Control Insights

All production lots receive multi-point testing for grade-defining parameters. Selection of raw tartrate salts comes through pre-approved vendor qualification with periodic retesting. Processing conditions—such as crystallization temperature profile, filtration effectiveness, and drying process—directly impact lot-to-lot purity and physical consistency. Analysts monitor for trace metals, chloride, sulfate, and moisture within each production step.

Batch-to-batch consistency depends on reactor charge control, filtration precision, and downstream packaging integrity. Release criteria reflect the application grade, with additional customer-defined criteria introduced after technical review. Control points focus on impurity source-identification: iron from process equipment, organics from side-reactions, and moisture from drying inefficiency receive the closest manufacturer monitoring. Resolving deviations requires root-cause assessment—often involving process traceability back to raw material batch or operator shift.
