Molecular Formula: C7H6Cl2
CAS Number: 95-73-8
Appearance: Colorless to pale yellow liquid, aromatic odor
Main Uses: Intermediate for dyes, pharmaceuticals, and agrochemicals
Physical Hazards: Flammable liquid and vapor, may form explosive mixtures with air
Health Hazards: Irritation to skin, eyes, and respiratory system; breathing high concentrations can cause dizziness or headaches
Environmental Hazards: Toxic to aquatic life, risk of bioaccumulation
GHS Symbols: Flame, exclamation mark, environment
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Component: 2,4-Dichlorotoluene
Purity: Usually exceeds 98%
Impurities: May include traces of 2,6-dichlorotoluene or other halogenated toluenes, lower than 2%
Chemical Class: Halogenated aromatic hydrocarbon
Eye Contact: Immediately flush with plenty of water for several minutes, remove contact lenses if present, seek medical attention if irritation persists
Skin Contact: Remove contaminated clothing, wash thoroughly with soap and water, consult a doctor if symptoms appear
Inhalation: Remove person to fresh air, keep at rest, seek medical help if symptoms like breathing difficulty occur
Ingestion: Rinse mouth, do not induce vomiting, call for medical advice
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical, or carbon dioxide, water spray can cool containers
Special Hazards: Fumes may include hydrogen chloride, phosgene, and carbon oxides in fire conditions
Firefighting Instructions: Wear self-contained breathing apparatus, keep safe distance, prevent run-off from entering drains
Personal Precautions: Evacuate area, ensure proper ventilation, wear appropriate protective equipment
Environmental Precautions: Avoid release to waterways or soil, contain the spill with non-combustible absorbent materials
Cleanup Methods: Collect spilled material for safe disposal, ventilate area, wash residues with plenty of water
Handling: Handle in well-ventilated spaces, avoid breathing vapors, use spark-proof tools, prevent static discharge
Storage: Store in tightly sealed containers away from heat, sparks, or open flames, keep away from oxidizers and acids, store in a cool, dry location
Work Hygiene: Wash hands and face after handling, change out of contaminated clothing before leaving the work area
Engineering Controls: Provide local exhaust or general ventilation, safety showers and eyewash stations should be readily available
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, flame-retardant clothing, respirators in inadequately ventilated areas
Occupational Exposure Limits: Specific regulatory limits are not universally established, but common sense calls for minimizing exposure as much as possible
State: Liquid
Odor: Aromatic, noticeable
Boiling Point: Approximately 211 °C
Melting Point: About -11 °C
Flash Point: Roughly 83 °C (closed cup)
Density: 1.3 g/cm³
Vapor Pressure: Low at room temperature
Solubility: Practically insoluble in water, mixes well with most organic solvents
Chemical Stability: Stable under normal conditions
Conditions to Avoid: Exposure to high temperatures, open flames, strong oxidizing agents
Incompatible Materials: Strong acids, strong oxidizers, alkali metals
Hazardous Decomposition: Hydrogen chloride, phosgene, carbon monoxide, and dioxide in fire
Likely Routes of Exposure: Inhalation, skin absorption
Acute Effects: Eye and skin irritation, coughing, shortness of breath, headache
Chronic Effects: Repeated or prolonged exposure could cause liver and kidney impairment
Sensitization: Not widely reported but should not be ruled out
Carcinogenicity Status: Not listed as carcinogenic by IARC, OSHA, or NTP
Aquatic Toxicity: Harmful to aquatic organisms, probable risk of long-lasting effects
Release Effects: Can contaminate soil and water, resistance to degradation leads to persistence
Bioaccumulation: Potential for moderate accumulation in aquatic life
Mobility in Soil: Limited due to low water solubility
Waste Disposal: Incinerate at approved facilities, follow local and national regulations for hazardous waste
Container Disposal: Empty containers may retain product residue, handle as hazardous even when emptied
