Concentration: ≥99% by weight
Impurities: Minimal, refer to manufacturer’s Certificate of Analysis
Other Ingredients: No additives or stabilizers commonly present
Inhalation: Move to fresh air promptly, keep victim warm and at rest, seek medical attention if breathing becomes difficult or symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin immediately with plenty of water for several minutes, wash with soap, seek medical attention for persistent irritation
Eye Contact: Rinse cautiously with water for at least fifteen minutes, lift eyelids occasionally, seek medical care
Ingestion: Do not induce vomiting, rinse mouth with water if conscious, seek immediate medical help
General Advice: Show physician this sheet, monitor breathing, provide supportive care as necessary
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct streams of water may spread fire
Specific Hazards: Vapors may form explosive mixtures with air, may emit toxic fumes of hydrogen bromide and carbon oxides if burned
Firefighter Protection: Self-contained breathing apparatus and full protective clothing required
Special Precautions: Cool containers exposed to fire with water spray, isolate risk area, prevent run-off from entering drains or water courses
Personal Precautions: Ventilate area, avoid sources of ignition, evacuate personnel not involved in emergency response
Protective Equipment: Chemical-resistant gloves, goggles, protective clothing, respiratory protection if ventilation inadequate
Spill Response: Absorb with inert material such as vermiculite or sand; collect residues in chemical waste container
Environmental Precautions: Prevent entry into waterways, sewers, or confined spaces
Decontamination: Wash spill site thoroughly after material pickup is complete
Handling: Use with local exhaust ventilation, avoid breathing vapors, wear protective equipment, keep away from heat and open flames, ground and bond containers when transferring liquid
Storage: Store in tightly closed containers in cool, dry, well-ventilated places, keep away from oxidizing agents, acids, bases, light, and moisture, segregate from food and incompatible chemicals
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing before entering common areas, do not eat, drink, or smoke where material is used
Occupational Exposure Limits: No established OSHA or ACGIH limits; ensure exposure kept as low as possible
Engineering Controls: Chemical fume hood, mechanical exhaust
Personal Protective Equipment: Nitrile gloves, lab coat or apron, chemical splash goggles; face shield for larger volumes
Respiratory Protection: Organic vapor respirator if ventilation is inadequate
Environmental Controls: Use spill containment and secondary containment measures for storage and transfer

Conditions to Avoid: Heat, sparks, open flame, exposure to air or moisture
Acute Toxicity: Harmful if swallowed, inhaled, or absorbed through skin
LD50 (oral, rat): Estimated 250-400 mg/kg
LD50 (dermal, rabbit): Data not available but likely to cause moderate toxicity
Routes of Entry: Inhalation, ingestion, skin, and eye contact
Chronic Effects: Prolonged exposure may cause liver or kidney effects, repeated skin contact can result in dermatitis
Special Sensitization: No evidence available for skin or respiratory sensitization
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Mutagenicity/Teratogenicity: No data available, avoid unnecessary exposure
Ecotoxicity: Toxic to aquatic life, fish, and invertebrates; may cause long-term adverse effects in the environment
Persistence and Degradability: Likely not rapidly biodegradable, persistent under most environmental conditions
Bioaccumulative Potential: Data unavailable, but structurally similar compounds show potential for bioaccumulation
Mobility in Soil: Low water solubility can limit mobility, but volatility increases atmospheric release
Other Adverse Effects: Prevent product from entering water courses to avoid environmental impact
Waste Disposal: Handle as hazardous waste; incineration is recommended method; do not allow into drains or sewers
Container Disposal: Triple rinse, puncture, and dispose of containers as hazardous waste per local, regional, national, and international regulations
