Chemical Name: L-Glutamine Tartrate
Synonyms: 2-Amino-4-carbamoylbutanoic acid monotartrate
CAS Number: 36687-82-8
Composition: L-Glutamine (approx. 53%), L-Tartaric acid (approx. 47%) by mass

Impurities: Water (<1%), residual solvents trace (<0.1%)
Inhalation: Remove exposed individual to fresh air. Blow nose or rinse mouth, seek medical attention for persistent irritation or coughing.
Skin Contact: Wash affected areas with plenty of soap and lukewarm water. Monitor for rash or persistent redness, consult a health professional if symptoms develop.
Eye Contact: Rinse with gentle stream of running water for at least 15 minutes, do not rub eyes. Remove contact lenses if worn and easy to do.
Ingestion: Rinse mouth, drink water to dilute small ingestion, do not induce vomiting. Medical attention recommended for significant or accidental ingestion.
Flammability: Not highly flammable. Fine dust can ignite with strong ignition sources in confined environments.
Suitable Extinguishing Media: Water spray, dry chemical extinguishers, CO2, or foam.
Unsuitable Extinguishing Media: Avoid direct heavy water jet, may spread powder.
Hazardous Combustion Products: May release nitrogen oxides, carbon monoxide, carbon dioxide on combustion.
Protective Equipment: Wear self-contained breathing apparatus and protective clothing. Avoid inhalation of combustion fumes.
Personal Precautions: Avoid dust generation, ventilate area, use respiratory protection if needed.
Spill Cleanup: Sweep up without generating dust, place into suitable waste containers. Rinse residue with water. Disinfect spill area.
Environmental Precautions: Prevent large amounts from entering drains, surface water, or soil. Notify local authorities if contamination risk appears.
Disposal: Dispose of in accordance with local, regional, and national regulations.
Precautions for Safe Handling: Wear appropriate PPE, avoid contact with skin, eyes, and clothing. Use in well-ventilated areas to reduce airborne particulates. Practice good industrial hygiene after handling.
Storage Conditions: Store in original tightly closed container, keep in a cool, dry, well-ventilated place, away from sunlight, heat sources, and incompatibles such as oxidizers.
Storage Temperature: Room temperature (15-25°C), stable under recommended conditions.
Incompatible Materials: Strong oxidizing agents, strong acids.
Exposure Limits: No established ACGIH or OSHA TLV. Keep exposure as low as reasonable.
Engineering Controls: Local exhaust or general room ventilation ensures airborne dust remains minimal.
Personal Protection: Safety glasses or goggles, nitrile gloves, lab coat recommended. Use NIOSH-approved dust mask or particulate respirator for significant airborne dust.
Hygiene Measures: Wash hands before eating, drinking, or smoking. Remove potentially contaminated clothing and wash before reuse.
Appearance: Fine, white powder
Odor: Faint, slightly acidic
pH (1% solution): 3.0 – 4.0
Melting Point: Decomposes above 185°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Fully soluble in water
Density: 1.3 - 1.5 g/cm³
Vapor Pressure: Not relevant for solids
Partition Coefficient (Log Kow): Not available
Flash Point: Not relevant for solids
Chemical Stability: Stable under normal storage and handling conditions
Incompatibility: Strong oxidizing substances can cause degradation. Acids or bases may alter composition.
Hazardous Decomposition Products: Produces oxides of carbon and nitrogen during combustion or decomposition.
Polymerization: Does not undergo hazardous polymerization.
Conditions to Avoid: Exposure to extreme temperatures, prolonged air or moisture contact.
Acute Toxicity: No human data, animal studies indicate low oral toxicity. High doses may cause gastrointestinal issues (nausea, diarrhea).
Chronic Toxicity: Not classified as carcinogen or mutagen. Long-term exposure not linked to chronic health concerns in current studies.
Skin/Eye Irritation: Mild irritation possible for sensitive individuals.
Sensitization: Rare but possible skin sensitization upon frequent/prolonged exposure.
Inhalation: May cause respiratory tract irritation with excessive airborne dust.
Other Data: Not classified as reproductive toxin, teratogen, or neurotoxin.
Ecotoxicity: Data limited. L-Glutamine and tartrate degrade naturally. Expected to present low acute risk to aquatic life in standard concentrations.
Persistence and Biodegradability: Compound is expected to biodegrade in soil and water due to its organic composition.
Bioaccumulative Potential: Not expected to bioaccumulate due to water solubility and biodegradability.
Mobility in Soil: Moderate to high mobility, water soluble, risk of leaching with runoff. Large release may impact nutrient balance.
Additional Information: Avoid direct release of large quantities into environment without proper containment.
Waste Treatment Methods: Dispose in accordance with federal, state, and local laws. Transfer to licensed waste disposal contractor for chemical waste.
Container Disposal: Rinse empty containers with water. Dispose of rinsate and container as hazardous waste.
Do Not: Pour down drains or waterways. Burning produces toxic fumes, avoid incineration unless controlled.
UN Number: Not regulated for transport.
UN Proper Shipping Name: Not applicable.
Transport Hazard Class: Non-hazardous material.
Packing Group: Not classified.
Environmental Hazards: Not considered a marine pollutant.
Special Precautions: Store in closed packaging, protect from humidity in transit. Mark packages per customs or local requirements.
