Chemical Name: 2,4-Dichlorotoluene
Common Uses: Intermediate for organic synthesis; precursor to agricultural and dye products; research material in synthetic chemistry
Chemical Formula: C7H6Cl2
Appearance: Colorless to pale yellow liquid
Odor: Aromatic, sharp typical of chlorinated hydrocarbons
Classification: Harmful if inhaled or swallowed; skin and eye irritant; suspected environmental hazard due to persistence
Symptoms: Irritation to eyes and skin; headache, dizziness, and nausea possible if inhaled; potential liver and kidney effects after chronic exposure
Fire Hazard: Flammable liquid with risk of vapors forming explosive mixtures with air
Health Risk: Repeated exposure may cause organ damage; use caution in enclosed areas
Main Component: 2,4-Dichlorotoluene (CAS 95-73-8), typically above 98% purity
Impurities: Trace levels of other dichlorotoluene isomers; common contaminants from synthetic processes
Toxic Additives: No added stabilizers or inhibitors in typical preparations
Inhalation: Remove affected person to fresh air; seek medical attention for symptoms such as coughing or breathing difficulty
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing; medical attention for persistent irritation
Eye Contact: Rinse gently with water for several minutes; lift eyelids to remove residues; seek medical advice
Ingestion: Do not induce vomiting; rinse mouth and consult a physician promptly
Suitable Extinguishing Media: Dry chemical, carbon dioxide, or alcohol-resistant foam; water spray for cooling exposed containers
Special Hazards: Combustion produces hydrogen chloride, carbon monoxide, and phosgene
Protective Equipment: Full protective gear including self-contained breathing apparatus
Precautions: Prevent runoff from contaminating drains or waterways; evacuate area if large quantities burn
Personal Precautions: Protective gloves, goggles, and respiratory protection recommended; ventilate area
Spill Management: Absorb small spills with inert material such as sand; for large spills, dike to contain and collect for disposal
Decontamination: Wash spill site after removal with water and detergent
Environmental Caution: Prevent product from entering drains, soil, or surface waters
Handling Practices: Use in well-ventilated locations; avoid inhaling vapors; avoid skin and eye contact
Storage Recommendations: Store in tightly closed containers away from direct sunlight, heat sources, or ignition points; segregate from acids and oxidizers
Hygiene Measures: Wash hands after use; change contaminated clothing promptly
Engineering Controls: Fume hoods or local exhaust ventilation minimize vapor exposure
Personal Protective Equipment: Chemical-resistant gloves; safety goggles; flame-retardant clothing; face shields for splash risk
Respiratory Protection: Filter masks if adequate ventilation cannot be ensured
Environmental Protection: Closed handling systems preferred to prevent volatilization and accidental spills
Physical State: Liquid at room temperature
Boiling Point: Around 210°C
Melting Point: Near -6°C
Density: Roughly 1.28 g/cm³
Vapor Pressure: Low to moderate, increases with temperature
Solubility: Insoluble in water; miscible with common organic solvents
Odor: Similar to chlorinated aromatic compounds; noticeable at low concentrations
Chemical Stability: Stable under normal temperature and pressure when stored appropriately
Reactive Hazards: Avoid strong oxidants and acids; potential for hazardous decomposition above 200°C
Hazardous Decomposition: Possible formation of hydrogen chloride, phosgene, and toxic organic vapors under fire conditions
Acute Effects: Short-term overexposure may cause severe irritation, central nervous system symptoms; elevated liver enzymes possible
Chronic Effects: Repeated inhalation or absorption can target kidneys and liver; sensitization rare but possible
Carcinogenicity: No strong evidence for cancer risk from current animal or human studies
Other Health Effects: Not known to cause birth defects based on animal data; process workers should use caution to minimize exposure
Aquatic Impact: Toxic to aquatic life with long-lasting effects; slow degradation raises concern about bioaccumulation
Soil Mobility: Binding to soil likely; limited movement in groundwater
Persistence: Not readily biodegradable; can remain in ecosystems for extended periods
Wastewater Concerns: Runoff or improper disposal risks contamination of surface water bodies
Waste Methods: Incineration in approved chemical waste facilities often preferred; avoid landfill disposal
Container Disposal: Triple rinse drums and containers before recycling or landfill, adhering to hazardous waste rules
Environmental Prevention: Never release into drains, sewers, or surface waters; observe local and international environmental disposal regulations
Road or Rail: Classified as hazardous cargo due to flammability and toxicity
Air Transport: Regulated as dangerous goods; robust packaging and special documentation needed
Marine Transport: Environmental warning applies to sea shipments; must label for marine pollutant warning
Incident Response: Emergency response guides recommend immediate isolation of area and specialized hazmat response in case of transport accidents
Chemical Inventories: Listed in major international chemical inventories such as the US TSCA and EU REACH
Exposure Limits: No established Occupational Exposure Limits in the US, but handle as hazardous material
Labeling: Requires GHS-compliant signal words, risk statements, and pictograms for flammability and toxicity
Other Regulations: Subject to hazardous substance regulations in many jurisdictions; compliance ensures worker and environmental safety
