Chemical Identity: Dibenzoyl-L-tartaric acid
Concentration: Pure substance 98%–100% typical
Impurities: No known significant impurity hazards reported; trace contaminants depend on synthesis
Ingredient Details: C18H14O8, CAS 2743-38-6, EINECS 220-368-5
Other Components: No additional components intentionally added
Eye Contact: Immediately flush with clean water for at least 10 minutes, hold eyelids open; seek medical attention if irritation persists
Skin Contact: Remove any contaminated clothing, wash affected area with mild soap and water, rinse thoroughly; medical attention if rash or irritation develops
Inhalation: Move victim to fresh air, support breathing; seek advice from a healthcare provider if symptoms such as coughing or shortness of breath do not resolve
Ingestion: Rinse mouth with water, do not induce vomiting, drink water to dilute substance; get medical help for discomfort or persistent symptoms
Most Important Symptoms: Slight irritation to eyes, skin, respiratory tract upon direct contact or exposure to significant dust
Suitable Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide for surrounding fire
Unsuitable Extinguishing Media: Avoid high-pressure water streams that could spread particles
Specific Fire Hazards: Decomposition in fire releases carbon oxides; does not ignite easily under typical storage
Protective Equipment: Wear self-contained breathing apparatus, full protective gear
Special Precautions: Move material away from fire area if safe; avoid inhaling combustion products; keep containers cool with water spray
Explosion Data: No reports of explosive dust-air mixture for this product
Personal Precautions: Wear gloves, eye protection, dust mask or respirator, avoid skin and eye exposure
Environmental Precautions: Block access to drains, prevent bulk releases to soil or water, collect spilled product for proper disposal
Clean-up Procedures: Sweep or vacuum up solid material (avoid dust generation), place into labeled, sealable containers for disposal; rinse area with water to remove residues
Reporting Requirements: Contact local authorities if large release threatens public health or environment
Handling Practices: Keep containers tightly closed, minimize dust generation and accumulation, use only with sufficient ventilation
Hygienic Practices: Wash hands after handling, avoid eating or smoking in work area, keep away from incompatible substances like strong oxidizers or bases
Storage Conditions: Store at room temperature, preferably below 25 °C; keep away from heat, light, and moisture; segregate from incompatible reactive materials
Packing Materials: Use sealed, chemical-resistant containers; label clearly
Occupational Exposure Limits: No national or international limits assigned for Dibenzoyl-L-tartaric acid
Engineering Controls: Local exhaust ventilation or fume hood in handling areas, containment for bulk processing
Personal Protective Equipment: Safety glasses with side shields, lab coat, impervious gloves, NIOSH-approved particulate respirator if dust present
Hygiene Measures: Remove and wash contaminated clothing before reuse, avoid hand-to-mouth contact
Environmental Protection: Retain and dispose of waste properly, avoid atmospheric releases
Appearance: White to off-white crystalline powder
Odor: Odorless or faint; no strong scent
Melting Point: 172–176 °C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Slightly soluble in water, soluble in ethanol, methanol
pH: No information for aqueous solutions, weakly acidic character
Density: 1.54 g/cm³
Vapor Pressure: Not significant; non-volatile
Partition Coefficient (log Pow): Data not available, expected low
Evaporation Rate: Not applicable for solids
Chemical Stability: Stable under standard laboratory and storage conditions
Reactivity: No hazardous reactivity reported; does not polymerize spontaneously
Conditions to Avoid: Avoid moisture, high temperatures, strong acids and bases, strong oxidizing agents
Incompatible Materials: Avoid strong alkalis, oxidizers, reducing agents; can react with such chemicals to form decomposition products
Decomposition Products: Carbon oxides, benzoic acid, minor organic fragments under extreme heat or fire
Routes of Exposure: Eyes, skin, inhalation of dust, ingestion
Acute Toxicity: Not acutely toxic; animal data show low oral toxicity
Symptoms: Eye and skin irritation, possible mild respiratory irritation, very high oral doses may cause headache or nausea
Chronic Toxicity: No evidence for carcinogenicity, mutagenicity, or reproductive toxicity
Sensitization: Not a known sensitizer
Further Information: Individuals with chronic respiratory conditions may experience symptoms when exposed to excessive dust
Ecotoxicity: No substantial aquatic or terrestrial toxicity expected for typical laboratory or industrial usage
Persistence and Degradability: Organic acid expected to degrade slowly in soil and water
Bioaccumulation Potential: Minimal, low log Pow expected; not likely to concentrate in food chains
Mobility in Soil: Low mobility due to limited water solubility, binds to organic material
Other Adverse Effects: Keep out of waterways in bulk; no data on endocrine disruption
Waste Methods: Collect residues and contaminated materials in sealed, properly labeled containers; send to licensed chemical waste disposal site
Disposal of Containers: Empty packages thoroughly before disposal, puncture or crush to prevent reuse, send to authorized handler
