Note to Doctor: Symptomatic treatment, monitor for late-developing respiratory symptoms
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, or water spray
Unsuitable Media: Direct water jet increases risk of hazardous decomposition products
Specific Hazards From Combustion: Releases toxic and corrosive gases including hydrogen fluoride, sulfur oxides, nitrogen oxides
Special Protective Equipment: Full SCBA and chemical-protective clothing required
Firefighting Procedures: Cool exposed containers with water spray, isolate fire area, prevent run-off from entering waterways, avoid inhalation of smoke or fumes
Explosion Hazards: No known explosive risk, but may produce exothermic decomposition if heated strongly
Personal Precautions: Evacuate area, ventilate, avoid dust/vapors, use personal protective equipment including gloves, goggles, chemical-resistant suit
Environmental Precautions: Prevent leakage or spillage from entering soil, sewers, or waterways; promptly contain contaminated materials
Cleanup Procedures: Absorb liquid spills with inert, non-combustible material (vermiculite, sand), collect in approved waste container, wash area with water and detergent while minimizing run-off
Methods for Disposal: Dispose of collected material following relevant national and regional chemical waste guidelines
Safe Handling Advice: Use under local exhaust ventilation, avoid skin and eye contact, do not ingest or inhale, do not breathe vapors or dust
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing, avoid eating or drinking near product
Storage Conditions: Store in tightly closed container in cool, dry, well-ventilated place, protect from moisture and direct sunlight
Incompatible Materials: Strong acids, strong bases, powerful oxidizers, materials that generate heat on contact with sulfonyl groups
Special Instructions: Segregate from incompatible chemicals, use secondary containment to minimize spill risk
Permissible Exposure Limits: No occupational exposure limits established; minimize exposure by following good lab practice
Engineering Controls: Local exhaust ventilation, safety showers, eyewash stations in work area
Personal Protective Equipment: Nitrile butyl gloves, chemical splash goggles, lab coats
Respiratory Protection: If ventilation inadequate, use NIOSH-approved respirator suitable for handling organic vapor and acid gases
Environmental Controls: Wastewater and exhaust management to reduce release to air and water, regular maintenance of ventilation and waste handling equipment
Appearance: Colorless to pale yellow liquid or crystalline solid (depends on temperature)
Odor: Mild characteristic odor, slightly pungent
Boiling Point: Decomposes before boiling
Melting Point: Between -10°C and 20°C (varies by purity)
Flash Point: Above 100°C (closed cup, estimate)

pH (1% solution): Slightly acidic (pH 5-6)
Vapor Pressure: Extremely low at ambient temperature
Relative Density: Approximately 1.5 g/cm³ (20°C)
Viscosity: High compared to simple organic solvents
Decomposition Temperature: Above 275°C (can undergo thermal breakdown releasing hazardous fumes)
Other Properties: Non-flammable under normal conditions, but decomposes under fire
Chemical Stability: Stable under recommended storage and use conditions
Reactivity: Can react violently with strong bases and oxidizing agents
Hazardous Reactions: May undergo exothermic breakdown if exposed to heat or strong acids/bases
Conditions to Avoid: Extended contact with moisture, extreme heat, incompatibles
Hazardous Decomposition Products: Hydrogen fluoride, sulfur dioxide, nitrous oxides, fluorinated organic compounds
Polymerization: Will not occur
Acute Toxicity: Not fully determined in humans; animal studies show moderate toxicity (oral LD50 in rodents typically over 200 mg/kg)
Skin Corrosion/Irritation: Causes moderate to severe irritation
Eye Damage/Irritation: Produces significant irritation, risk of corneal damage with extended contact
Respiratory Effects: Dust or vapor inhalation creates coughing, breathlessness, sore throat
Sensitization: Unlikely based on available data, but repeated exposure could cause skin sensitization
Repeated Dose Toxicity: Prolonged or frequent contact can dry or crack the skin, respiratory effects include chronic cough and throat irritation
Carcinogenicity/Mutagenicity/Reproductive Toxicity: No reliable studies indicate risk, classified as not expected to be carcinogenic by IARC or NTP; insufficient long-term data
Other Effects: Ingestion or inhalation may impact nervous system, gastrointestinal tract
Ecotoxicity: Toxic to aquatic organisms, fish and algae in freshwater and marine systems
Persistence and Degradability: Degrades slowly; not expected to biodegrade rapidly in standard wastewater treatments
Bioaccumulative Potential: Potential for bioaccumulation in aquatic environments not excluded, monitor use near sensitive habitats
Mobility in Soil: Mobile in water, could leach to subsoil, contaminating water tables
Other Adverse Effects: Requires containment, runoff could cause down-stream ecosystem changes
Disposal Methods: Dispose as hazardous waste according to local/national regulations, incinerate only in chemical incinerator with afterburner and scrubber
Contaminated Packaging: Rinse containers, dispose of as hazardous chemical waste; do not reuse empty packaging
