Suitable Extinguishing Media: Use carbon dioxide (CO2), dry chemical powder, or alcohol-resistant foam
Unsuitable Media: Do not use water jets directly on product
Hazards from Combustion: Emits toxic fumes of carbon oxides (CO, CO2) under fire conditions
Protective Equipment: Wear full protective gear including self-contained breathing apparatus
Special Hazards: May form combustible dust clouds; risk increases if stored in poorly ventilated area
Personal Protection: Evacuate unnecessary personnel, wear protective gloves, safety glasses, dust mask
Environmental Precautions: Prevent product from entering drains or water bodies
Clean-Up Method: Sweep up with non-sparking tools, avoid generating dust; place in labeled waste container for disposal
Decontamination: Wash spill area thoroughly with water after complete removal
Ventilation: Ensure adequate ventilation during and after clean-up
Handling Advice: Handle with dry hands, avoid contact with skin and eyes, use only in well-ventilated areas
Safe Practices: Use local exhaust ventilation; avoid inhaling dust or vapors
Storage Conditions: Store tightly closed in cool, dry, well-ventilated area away from direct sunlight and incompatible substances
Incompatibles: Strong oxidizing agents, strong bases; product may hydrolyze slowly in moist air
Storage Containers: Use only containers made from compatible materials such as HDPE, glass
Exposure Limits: Not established for this substance; control possible dust and vapor
Engineering Controls: Laboratory fume hood, local ventilation required for bulk handling
Personal Protective Equipment:
- Skin: Chemical-resistant gloves (nitrile, PVC)
- Eyes: Safety goggles with side shields
- Respiratory: Dust mask or half-mask respirator with P2 filter
- Clothing: Lab coat, protective boots if handling large quantities
Hygiene Measures: Wash hands before breaks and after handling; no eating or drinking in work area
Appearance: White to off-white crystalline powder
Odor: Faint, ester-like
Molecular Weight: 178.14 g/mol
Melting Point: 52-56°C
Boiling Point: 156–158°C at 16 mmHg (vacuum)

pH: Neutral to slightly acidic (4.5–5.5, 1% solution)
Flash Point: Above 130°C
Vapor Pressure: Not significant at room temperature
Chemical Stability: Stable under recommended storage conditions
Reactivity: Can react with strong oxidizers or bases
Decomposition: Prolonged heating produces carbon oxides; hydrolyzes slowly in presence of moisture
Polymerization: Does not undergo hazardous polymerization
Other risks: Hygroscopic, can absorb moisture from air leading to clumping or hydrolysis over time
Acute Toxicity: Data limited; estimated LD50 (oral, rat) >2000 mg/kg
Skin Contact: May cause irritation, redness, itching upon repeated exposure
Eye Contact: May lead to redness and watering
Respiratory Effects: Respiratory tract irritation possible from dust
Chronic Effects: No long-term effects reported in available literature
Sensitization: No evidence from animal studies, caution for allergy-prone individuals
Mutagenicity/Carcinogenicity: No data supporting carcinogenicity or genetic toxicity
Aquatic Toxicity: Not classified as environmentally hazardous, but avoid release to waterways
Soil Impact: Degrades slowly, does not bioaccumulate
Mobility: Water soluble, may migrate if spilled in large quantities
Degradability: Expected to degrade by hydrolysis and microbial action over weeks
Persistence: Not persistent, breaks down naturally with exposure to moisture and bacteria
Waste Treatment: Collect all waste and spill residues into marked containers for disposal
Disposal Methods: Utilize licensed chemical disposal contractor; incineration preferred
Waste Code: Not classified as hazardous waste in most jurisdictions, but must confirm with local regulations
