DI-O-Benzoyl-D-Tartaric Acid brings a distinctive name and an equally distinctive set of properties. This organic compound develops as a derivative of tartaric acid, where both hydroxyl groups are replaced with benzoic acid esters. With a molecular formula of C18H14O8, and a structural backbone that stays true to the D-tartaric orientation, DI-O-Benzoyl-D-Tartaric Acid positions itself as a nuanced player in both the fine chemicals market and the research sector. Physical appearance often comes in the form of white or almost white crystalline powder or flakes. The esterification with benzoyl groups creates a substance more hydrophobic compared to its parent acid, impacting its solubility profile and handling requirements.
Density ranges around 1.4 g/cm³ at ambient temperature, with a melting point commonly noted between 124°C and 130°C. The material typically presents itself as free-flowing white crystals, powder, or thin crystalline flakes, depending on the crystallization process and the purity achieved during manufacturing. DI-O-Benzoyl-D-Tartaric Acid resists moisture quite well, but temperature control remains important to avoid decomposition or unwanted hydrolysis. Solubility sits low in water but jumps in organic solvents like methanol, chloroform, and ethyl acetate. This solubility behavior directly influences application choices, particularly for chiral resolution in the pharmaceutical field. Unlike some raw materials that blend without hassle, the need for pure organics like DI-O-Benzoyl-D-Tartaric Acid means attention stays on avoiding contamination or exposure to reactive environments.
The signature structure features two aromatic benzoyl groups anchored on the tartaric acid’s central four-carbon backbone, bringing not only increased molecular weight but also greater rigidity and defined stereochemistry. Labs and production units lean on this molecule as a chiral resolving agent, most notably for separating racemic bases and alcohols. Because each molecule retains chirality and offers dual benzoyl arms, enantiomeric excess can be achieved at scales where lesser agents struggle. Beyond chiral resolution, specialty sectors look to DI-O-Benzoyl-D-Tartaric Acid as a chemical intermediate, a tool for asymmetric synthesis, and an occasional additive for advanced polymer research. Precise molecular control has become central to many performance chemicals, and DI-O-Benzoyl-D-Tartaric Acid offers a practical solution to those demands.
Safe use remains critical. DI-O-Benzoyl-D-Tartaric Acid does not fall under routine hazardous substances, but standard chemical hygiene applies: avoid inhalation, skin or eye contact, and unprotected handling. Powder and flake forms can generate airborne particles, so containment and use of personal protective equipment matter a great deal. No significant harmful breakdown products are expected under ambient conditions. Storage in tightly closed containers protects it against moisture uptake and accidental hydrolysis; temperature stability means shelf life can extend, provided humidity and heat stay controlled. Packaging often references UN or hazardous shipping codes, though DI-O-Benzoyl-D-Tartaric Acid travels under its own HS Code: 29181990 for customs purposes, classifying it as a carboxylic acid derivative.
Specifications cover purity, typically above 98%, residual solvents, and crystal habits. Bulk users often require full certificates of analysis documenting density, melting point, and trace impurities—parameters that determine suitability for analytical or manufacturing processes. Differentiation by particle size, such as fine powder versus flakes or pearls, only happens based on drying and milling during production. Project specifications dictate these small but important physical differences, since they affect dissolution rates and batch-to-batch reproducibility. This is especially relevant for high-precision applications in pharma and specialty chemicals, where raw material consistency preserves process reliability.
In the global market, DI-O-Benzoyl-D-Tartaric Acid forms a niche but steady segment. Suppliers in Europe, North America, and Asia maintain focus on quality and technical support, since this compound often appears on raw materials lists for high-value finished goods. Sourcing teams look beyond just price and lead time; traceability, batch QA, and documentation for safe shipment take precedence. It is common to see users in pharmaceutical synthesis, agrochemical R&D, and advanced materials hinge their process control on the reliability of each new batch of DI-O-Benzoyl-D-Tartaric Acid procured.
Some key challenges—like variable purity, risk of cross-contamination, or supply disruptions—impact users relying on consistent performance. To counter this, direct relationships with manufacturers rather than brokers often provide better lot traceability and technical insight. On-boarding third-party analytical testing before accepting large shipments has become a smart move for buyers, catching specification discrepancies before they hinder a key production run. Environmental controls during storage—dry air, stable temperature, segregated chemical zones—cut the risk of accidental degradation or contamination. For users who need to source DI-O-Benzoyl-D-Tartaric Acid on a regular schedule, forward contracts and dual-sourcing strategies keep inventory levels stable despite global logistics unpredictability.
With a molar mass of 358.30 g/mol, the molecule delivers a robust analytical footprint. Infrared spectroscopy confirms key ester and carboxylic functionalities, while NMR provides an unequivocal look at both aromatic and aliphatic regions. X-ray crystallography sometimes verifies absolute stereochemistry, a non-negotiable in enantioselective applications. Experience shows that careful lot screening using HPLC alongside mass spectrometry solidifies quality control, especially when DI-O-Benzoyl-D-Tartaric Acid serves as a chiral selector.
The choice between powder, flakes, or crystals often follows end-use requirements—ease of handling, speed of dissolution, and susceptibility to static. Bulk handlers and advanced research labs typically prefer free-flowing powders for volumetric dosing, while process chemists sometimes request larger crystals or flakes for slow dissolution protocols. This attention to granular details ensures each user derives the highest functional benefit from each shipment.
