Inhalation: Move affected person to fresh air immediately; if any coughing or symptoms persist, seek medical attention
Skin Contact: Remove contaminated clothing; wash skin area thoroughly under running water, use soap if available
Eye Contact: Rinse with plenty of water for several minutes, lifting eyelids; seek help if irritation continues
Ingestion: Rinse mouth; do not induce vomiting; consult a physician if feeling unwell or if a large amount was ingested
Advice for Medical Personnel: Treat symptoms; specific antidote is not known; monitor respiratory, eye, and skin health closely
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Specific Hazards: Decomposition may release carbon oxides and toxic fumes if product is burned; avoid breathing combustion gases
Protective Equipment: Firefighters should use full protective gear and self-contained breathing apparatus
Firefighting Procedures: Move containers away from fire area; cool adjacent containers with water spray to prevent overheating or rupture
Other Considerations: Fine powder may present dust explosion risk if dispersed in air and exposed to ignition sources in large enough amounts
Personal Precautions: Use appropriate personal protective equipment—gloves, eye protection, dust mask
Environmental Precautions: Prevent runoff into drains, soil, or waterways; sweep up carefully
Methods for Cleaning Up: Collect material mechanically—avoid generating dust clouds; place in labeled containers for disposal; ventilate area after cleanup
Reference to Other Sections: Refer to section on Exposure Controls and Personal Protection for safe handling guidelines
Handling: Use only in well-ventilated areas; minimize dust generation; avoid direct contact with skin and eyes; do not eat, drink, or smoke in work area
Storage: Store in cool, dry location; keep container tightly closed in a chemical-resistant container; avoid exposure to light, moisture, and heat sources
Incompatible Materials: Store away from strong acids, strong oxidizers, and bases to prevent unwanted reactions
Hygiene Practices: Wash hands thoroughly after handling even if gloves are used; change contaminated clothing promptly
Occupational Exposure Limits: No occupational exposure limits established for this substance under most national regulations
Engineering Controls: Work in chemical fume hood for large quantities or procedures with dust; use local exhaust ventilation if available
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or equivalent), safety goggles, lab coat; use dust mask if appropriate
Respiratory Protection: Dust mask or respirator with particulate filter if air concentration may reach nuisance levels
Environmental Controls: Prevent release outside designated work area; properly dispose of or store collected dust and waste material
Appearance: White to off-white crystalline powder
Odor: Odorless or faint aroma indistinguishable at normal concentrations
Melting Point: 165–170°C
Boiling Point: Decomposes upon boiling without boiling in traditional sense
Solubility: Sparingly soluble in water; more soluble in organic solvents such as ethanol, methanol, and acetone
pH (1% solution): Slightly acidic
Density: Approximately 1.4 g/cm³ at room temperature
Vapor Pressure: Negligible at ambient conditions
Partition Coefficient (log Kow): No data available; not expected to bioaccumulate significantly
Flammability: Not easily ignited, but fine dust may pose fire risk if dispersed near ignition source
Chemical Stability: Stable under recommended storage conditions for laboratory settings
Incompatibility: Reacts with strong acids, strong bases, and oxidizing agents—may liberate heat or toxic substances in such reactions
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, potentially minor organic acid vapors when strongly heated or combusted
Polymerization: Will not undergo hazardous polymerization
Other Conditions to Avoid: Avoid exposure to strong light, temperatures above 60°C, and excessive humidity which can degrade product quality or stability
Acute Toxicity: No significant acute oral, dermal, or inhalation toxicity documented at typical laboratory handling levels; large exposures could irritate
Skin and Eye Irritation: May cause redness or temporary discomfort; prolonged contact raises risk of reaction
Respiratory Effects: Dust could cause mild respiratory tract irritation; use adequate ventilation to limit exposure
Sensitization: No data suggesting skin or respiratory sensitization, but precautions appropriate for laboratory chemicals stay in place
Chronic Effects: No long-term hazard information available from standard sources; use general caution
Mutagenicity, Carcinogenicity, Reproductive Toxicity: No studies available, not expected to present such risks for laboratory handling
Medical Conditions Aggravated by Exposure: Pre-existing respiratory conditions or chemical sensitivities may increase risk of symptoms on exposure
Ecotoxicity: No specific data available; not expected to present significant environmental risk at small laboratory scales
Persistence and Degradability: Expected to be biodegradable over time; breakdown in environment generally occurs via natural microbial action
Bioaccumulation Potential: Not expected to bioaccumulate in aquatic organisms due to low water solubility and molecular structure
Mobility in Soil: Low mobility; not likely to leach extensively due to physical and chemical properties
Additional Notes: Prevent release into surface water, sewer, or soil in populated areas; residues should be disposed as chemical waste
Disposal Methods: Dispose of contents/container in accordance with local/regional/national regulations; do not discharge into environment uncontrolled
Contaminated Packaging: Triple-rinse containers and dispose of as hazardous waste according to site policy
Waste Code: Assign based on local guidelines for organic laboratory chemicals
UN Number: Not regulated as dangerous goods for transport via road, rail, air, or sea under international transport regulations
Proper Shipping Name: Di-P-Toluoyl-D-Tartaric Acid; ship as non-dangerous goods
Transport Hazard Class: None assigned
