Molecular Weight: 182.7 g/mol
EC Number: 205-406-3
Other Components: Usually contains no additives or stabilizers unless otherwise specified by supplier
Eye Contact: Rinse cautiously with water for at least 15 minutes; remove contact lenses if possible; get medical attention immediately
Skin Contact: Remove contaminated clothing; wash skin with plenty of soap and water; seek medical attention if irritation develops or persists
Inhalation: Move to fresh air immediately; assist breathing if necessary; seek medical help for cough, breathing difficulty or persistent discomfort
Ingestion: Rinse mouth thoroughly with water; do not induce vomiting; obtain immediate medical assistance
Note for Clinicians: Provide symptomatic and supportive treatment; avoid direct exposure when examining contaminated wounds or burns
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide (CO2), foam; use water spray only to cool containers, not to extinguish flames directly
Specific Hazards: Releases toxic gases including hydrogen chloride and phosgene upon combustion; can create flammable vapors at high temperatures
Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus
Special Procedures: Approach from upwind location; cool exposed containers with water spray; avoid direct water stream on liquid chemical
Personal Precautions: Evacuate unprotected personnel; shut off all sources of ignition; ventilate area; use personal protective equipment including gloves and goggles
Environmental Precautions: Prevent chemical from entering drains, water bodies, or soil; report major leaks to appropriate environmental authority
Cleanup Methods: Absorb small spills with inert material such as sand or vermiculite; collect in sealed containers for disposal; ventilate and clean contaminated area thoroughly
Handling Precautions: Wear protective clothing, gloves, and safety glasses; avoid inhalation, ingestion or contact with skin or eyes; use local exhaust ventilation where possible
Storage Conditions: Store in tightly-sealed containers in a cool, dry, well-ventilated place away from heat sources, open flames, moisture, and incompatible materials such as strong oxidizers or acids
Special Storage Requirements: Keep container tightly closed; label containers clearly; store away from direct sunlight or sources of ignition; segregate from food and beverages
Incompatibilities: Strong oxidizing agents, acids, bases, water (may hydrolyze to produce hazardous gases)
Exposure Limits: No established occupational exposure limits; minimize exposure as much as practical
Engineering Controls: Use mechanical exhaust or fume hood to reduce exposure; install eyewash stations and safety showers near work area
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, protective lab coat or chemical-resistant clothing, respiratory protection (N95 or higher) for insufficiently ventilated areas
Hygiene Measures: Wash hands and face after handling; remove contaminated clothing and wash thoroughly before reuse; do not eat, drink, or smoke where chemical may be present
Appearance: Colorless to pale yellow liquid
Odor: Aromatic, pungent
Boiling Point: 238-242°C
Melting Point: -10°C
Flash Point: Above 110°C (closed cup)
Solubility: Insoluble in water, soluble in organic solvents such as benzene, ether, and chloroform
Density: 1.012 g/cm³
Vapor Pressure: < 0.1 mmHg at 20°C
Viscosity: Not available
pH: Not applicable to organic compounds
Auto-Ignition Temperature: Not well defined
Chemical Stability: Stable under ordinary conditions if kept in airtight container away from moisture
Conditions to Avoid: Prolonged exposure to air, high temperature, direct sunlight, open flames, or incompatible chemicals
Reactivity: Reacts with strong oxidizers and bases; hydrolyzes in contact with water, releasing hydrogen chloride gas
Hazardous Decomposition Products: Hydrogen chloride, chloro-organic byproducts, and possibly phosgene; decomposition can accelerate in fire
Polymerization: Not expected under normal handling and storage conditions
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Can provoke skin and respiratory tract irritation, symptoms including coughing, redness, and pain; ingestion may cause nausea, abdominal pain, and chemical pneumonitis if aspirated
Chronic Effects: Repeated exposure may lead to dermatitis or asthma-like symptoms; potential for skin sensitization with prolonged or repeated contact
Carcinogenic Status: Not listed as carcinogenic by IARC, NTP or OSHA
Other Data: No definitive data on reproductive or developmental toxicity in humans; animal studies limited
Persistence and Degradability: Not readily biodegradable in soil or aquatic environments
Bioaccumulation Potential: May bioaccumulate in aquatic organisms
Aquatic Toxicity: Harmful to fish, daphnia, and other aquatic life; toxic effect increases with concentration and exposure duration
Mobility in Soil: Low solubility means slow migration; may persist in soil or sediment
Other Adverse Effects: Avoid discharge into environment; data gap on long-term environmental impacts
Waste Treatment Methods: Collect chemical waste in clearly labeled, tightly closed containers; do not dump down drains or release into environment
Recommended Disposal: Dispose through licensed chemical disposal contractor; incinerate using approved high-temperature incineration
Contaminated Packaging: Triple rinse with suitable solvent and then puncture or crush before disposal as chemical waste
Local Regulations: Follow all applicable local, state, and national guidelines for hazardous waste handling and disposal
