Chemical Name: Diethyl Tartrate
Concentration: 100% pure or as specified by the supplier
Impurities: Minor trace solvents or stabilizers may appear in manufacturing batches; explicit details are generally available in supplier analysis reports.
Inhalation: Move person to fresh air. Restore breathing if needed. Obtain medical attention for persistent symptoms.
Skin Contact: Remove contaminated clothing. Cleanse area with mild soap and water for many minutes. Medical follow-up recommended for irritation.
Eye Contact: Rinse eyes gently with copious water, holding eyelids open. Remove contact lenses if present. Continue rinsing for at least 15 minutes. Get medical attention for irritation.
Ingestion: Rinse mouth with water. Do not induce vomiting. Seek immediate medical guidance.
Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray.
Hazardous Combustion Products: Carbon oxides including CO and CO₂ develop under fire.
Protective Equipment: Firefighters should wear full-body suit and breathing apparatus.
Precautions: Remove containers near fire. Vapors may form explosive mixtures with air if temperatures are high enough.
Personal Precautions: Wear gloves, goggles, and protective clothing to avoid direct contact. Ventilate spill area.
Spill Containment: Prevent entry into drains and sewers. Use absorbent material such as sand or inert compound.
Cleanup Methods: Collect and seal contaminated absorbent for disposal. Wash surfaces thoroughly after removal.
Handling: Avoid inhalation, eye or skin contact. Always wash hands after use. Use in fume hood or well-ventilated area.
Storage Conditions: Store in tightly closed containers. Place in cool, dry, and well-ventilated spot. Keep away from strong oxidizers and chemicals incompatible with esters. Protect from temperature extremes and direct sunlight. Label containers clearly for safety auditing purposes.
Exposure Limits: No established occupational exposure limits exist for Diethyl Tartrate. Standard precautions apply.
Engineering Controls: Work under local exhaust ventilation. Eye-wash and safety showers in laboratory setting add a layer of protection.
Personal Protection: Chemical-resistant gloves, well-fitting splash goggles, lab coats, closed footwear. Good hygiene practices, such as not consuming food or drinks where chemicals are handled, contribute to safety.
Appearance: Clear, colorless liquid or low-melting solid
Odor: Mild, fruity odor
Boiling Point: 142°C at 18 mmHg (lower pressure)
Melting Point: -15°C to -10°C (varies slightly by enantiomer)
Solubility: Insoluble in water, miscible with alcohols and ethers
Density: 1.21 g/cm³ at 20°C
Vapor Pressure: Low under ambient conditions
Flash Point: 123°C (closed cup)
Viscosity: Moderate, consistent with small esters
Specific Gravity: About 1.207 (20°C/4°C)
Chemical Stability: Stable under normal conditions. Prolonged exposure to high temperatures or direct sunlight may cause decomposition.
Incompatible Materials: Strong oxidizers, strong acids, alkalis
Decomposition Products: On burning, forms carbon oxides
Hazardous Reactions: Vigorous reaction unlikely unless combined with reactive agents.
Acute Toxicity: LD₅₀ (oral-rat): >5000 mg/kg
Skin Contact: May cause irritation, redness, or dryness
Eye Contact: Can result in watery, irritated eyes
Inhalation: Inhalation of vapors or mists may cause mild respiratory discomfort
Chronic Effects: No data available indicating carcinogenic, mutagenic, or reproductive toxicity events at normal exposure.
Sensitization: May trigger skin sensitization in individuals prone to allergies.
Aquatic Toxicity: No specific data, although most simple esters display moderate ease of biodegradation. Low risk for acute hazardous effects in aquatic settings.
Persistence and Degradability: Likely to undergo bio-degradation via hydrolysis and microbial action
Bioaccumulation Potential: Generally low due to solubility and molecular structure
Mobility in Soil: May migrate in liquid form, but moderate environmental hazard due to low toxicity.
Waste Treatment Methods: Dispose of as hazardous waste, following local, regional, and national regulations.
Container Disposal: Triple-rinse empty bottles. Deface labels before safe recycling or landfilling.
Disposal Precautions: Keep material segregated from general household waste. Use proper registries for chemical waste.
UN Number: Not regulated for surface transport in most countries
Proper Shipping Name: Diethyl Tartrate
Transport Hazard Class: Not classified as hazardous for transport
Packing Group: Not assigned
