Chemical Name: 4-Chlorobenzotrifluoride
Chemical Formula: C7H4ClF3
Common Synonyms: Parachlorobenzotrifluoride, PCBTF
Appearance: Clear, colorless liquid
Odor: Aromatic, distinctive somewhat sweet smell
Molecular Weight: 180.55 g/mol
Hazard Class: Flammable liquid and vapor
Health Risks: Respiratory tract and eye irritation, moderate skin hazard, possible harm to aquatic systems
Signal Word: Warning
Pictograms: Flame, Exclamation Mark
Precautionary Statements: Avoid breathing vapors, keep away from ignition sources, wash exposed skin thoroughly, do not release into the environment
Ingredient: 4-Chlorobenzotrifluoride
Concentration: Up to 99%
CAS Number: 98-56-6
Inhalation: Move to fresh air, seek medical attention if symptoms appear
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and continue rinsing
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention if feeling unwell
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide
Specific Hazards: Vapors may form explosive mixtures with air, toxic fumes if combusted
Protective Equipment: Self-contained breathing apparatus, full protective suit
Special Procedures: Containers near fire should be cooled with water spray, avoid inhalation of combustion products
Personal Precautions: Remove ignition sources, ventilate area, avoid direct contact with skin or eyes
Spill Containment: Use inert absorbent material like sand or vermiculite, collect for proper disposal
Environmental Precautions: Prevent entry into water courses and sewers, report releases as required by local legislation
Safe Handling: Handle in well-ventilated locations, keep away from open flames and hot surfaces, use spark-proof tools and explosion-proof equipment
Storage Conditions: Store tightly closed in original container, out of sunlight, in a cool dry area with proper grounding and bonding for flammable materials
Exposure Limits: No established OSHA or ACGIH limits, but minimize exposure due to irritant effects
Engineering Controls: Local exhaust ventilation, vapor suppression where possible
Personal Protection: Safety glasses or goggles, nitrile or neoprene gloves, flame-retardant clothing, approved respirator during high exposure risk
Boiling Point: Around 139°C (282°F)
Flash Point: Approximately 43°C (109°F), closed cup
Melting Point: -29°C (-20°F)
Density: About 1.35 g/cm³ at 20°C
Vapor Pressure: 4.2 mmHg at 25°C
Solubility: Very limited in water, miscible with organic solvents
Vapor Density: Greater than air
Chemical Stability: Stable under recommended storage conditions, sensitive to strong oxidizers and bases
Reactivity: Can react vigorously with strong oxidizing agents
Decomposition Products: Hydrogen chloride, phosgene, carbon monoxide, carbon dioxide, hydrogen fluoride in fire or high heat
Possible Exposure Routes: Inhalation, skin and eye contact, ingestion rare and dangerous
Acute Toxicity: LD50 (oral, rat) about 13,000 mg/kg, low acute toxicity in animals
Irritation: Eyes and upper respiratory tract especially sensitive to vapor concentrations; repeated or prolonged exposure can lead to skin dryness or cracking
Long-Term Effects: Evidence of chronic toxicity lacking but minimize repeated exposure due to solvent-like action and organ impacts observed in other chlorinated aromatics
Environmental Risks: Harmful to fish and aquatic organisms if released in large quantities; not readily biodegradable
Mobility: Expected to have low mobility in soil due to poor water solubility
Persistence: Tends to persist in the environment due to chemical inertness
Bioaccumulation: May accumulate in aquatic life with ongoing exposure
Proper Disposal: Dispose of contents and containers according to local, regional, and national regulations for organic solvents
Preferred Methods: High-temperature incineration with emission controls; avoid landfilling bulk liquids
UN Number: 2234
Proper Shipping Name: 4-Chlorobenzotrifluoride
Hazard Class: 3 (Flammable liquid)
Packing Group: III
Transport Precautions: Keep tightly sealed, upright, and protected from physical damage during shipping, follow all hazardous material regulations
Regulatory Listings: Listed on global chemical inventories like TSCA, DSL
Labeling Required: Flammable, irritant warnings on all packaging and bulk shipments
Compliance Notes: Users must follow workplace safety, environmental release, and transportation laws as established in their region, and track changes in regulatory standards affecting aromatic solvent use
