Concentration: 95–100% (depending on source)
Inhalation: Remove from exposure area to fresh air, keep victim calm, seek medical attention immediately
Skin Contact: Remove contaminated clothing, thoroughly wash skin with soap and water for at least 15 minutes, seek medical advice
Eye Contact: Rinse eyes immediately with water for at least 15 minutes, lifting eyelids occasionally, seek prompt medical evaluation
Ingestion: Rinse mouth if conscious, do not induce vomiting, seek immediate medical assistance
Most Important Symptoms: Nausea, headache, abdominal pain, potential kidney damage
Immediate Medical Attention Required: Yes, especially after significant exposure or suspected poisoning
Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, or foam; avoid water jets
Specific Hazards: Toxic fumes of carbon monoxide, carbon dioxide, nitrogen oxides, chlorinated compounds may evolve during fire
Protective Equipment: Wear self-contained breathing apparatus and chemical protective clothing
Special Precautions: Avoid runoff from firefighting entering drains or waterways
Personal Precautions: Wear chemical-resistant gloves, goggles, and suitable respiratory protection
Environmental Precautions: Prevent further leakage or spillage if safe to do so, do not let product enter drains, surface, or groundwater
Method for Cleanup: Clean up spills quickly using inert absorbent materials, dispose of in labeled chemical waste containers, ventilate area, decontaminate surfaces with 10% bleach solution (sodium hypochlorite) if possible, wash hands and surfaces thoroughly after dealing with contamination
Precautions for Safe Handling: Use containment and local exhaust ventilation, use measures to minimize dust formation, avoid breathing vapors or dust, handle with care and avoid spills, avoid contact with skin, eyes, and clothing, do not eat, drink, or smoke while using this material
Conditions for Safe Storage: Store in tightly closed containers, protected from light, at 2–8°C (refrigerated conditions), segregate from incompatible substances (strong acids/alkalis, oxidizers), store away from foodstuffs, labeled and secure storage for toxic substances, maintain an up-to-date inventory of holdings
Exposure Limit Values: No established occupational exposure limits in many countries, minimize exposure as much as possible
Engineering Controls: Use biological safety cabinet or chemical fume hood, local exhaust ventilation
Personal Protection: Wear lab coat, impervious gloves (nitrile, neoprene, or similar), chemical safety goggles, respiratory protection (N95 or better) if dust or aerosols are generated
Hygiene Measures: Wash hands and face before breaks and at end of work, separate contaminated clothing from street clothes, launder before re-use, do not eat or drink in work areas

Auto-ignition Temperature: Not determined
Viscosity: Not applicable as a solid
Explosion Properties: May form explosive dust-air mixtures
Chemical Stability: Stable under recommended storage conditions (refrigerated, protected from light)
Reactivity: Low under normal handling, avoid strong oxidizers and reducing agents
Possibility of Hazardous Reactions: None under normal storage and use conditions
Decomposition Products: Emits toxic fumes of carbon monoxide, carbon dioxide, nitrogen oxides, chlorinated compounds on thermal decomposition
Conditions to Avoid: Exposure to light, heat, incompatible materials (acids, alkalis, oxidizers)
Acute Toxicity Data: Oral LD50 (rat): 28 mg/kg, highly toxic
Routes of Entry: Oral, inhalation, dermal, ocular
Chronic Effects: Nephrotoxic, teratogenic, carcinogenic; long-term exposure can impair kidney function and increase cancer risk
Carcinogenicity: Classified as possible human carcinogen (Group 2B, IARC); evidence from animal studies for kidney tumors
Mutagenicity: Evidence from in vitro and animal studies suggests genotoxic potential
Reproductive Toxicity: Effects observed in animal reproductive studies; avoidance of exposure is essential, especially for pregnant individuals
Symptoms of Overexposure: Nausea, headache, abdominal distension, renal dysfunction, fatigue, potential immune suppression
Ecotoxicity: Harmful to aquatic organisms and likely to cause long-term effects in the aquatic environment
Persistence and Degradability: Stable and persistent in soils and waters, degradation by biotic and abiotic means is slow
Bioaccumulative Potential: High (log Kow 4.6); potential to accumulate in organisms and enter the food chain
Mobility in Soil: Limited water solubility restricts migration, but may bind to soil and organic matter
Other Adverse Effects: Contributes to contamination of crops and animal products, posing a risk to human and animal health indirectly
Disposal Method: Collect waste in sealed, labeled containers; coordinate disposal via licensed hazardous waste management company
Special Precautions: Do not flush to drains, sewers, or landfill; incinerate contaminated material at high temperatures with suitable flue gas cleaning
Disposal of Contaminated Packaging: Treat as hazardous waste; decontaminate if possible or dispose of as laboratory chemical waste
