Chemical name: 3-Chloro-2-Methylpropene
Other names: Isoprenyl chloride
Common uses: Synthesis of pharmaceuticals, chemical intermediates
Appearance: Colorless, flammable liquid, distinct sharp odor
Odor threshold: Sharp, pungent scent easily noticed upon opening a container
Primary application: Key starting compound in organic chemistry labs and chemical manufacturing
CAS number: 563-47-3
Health risks: Can cause eye and skin burns, inhalation may irritate airways, high concentrations cause central nervous system effects, possible carcinogen with extended exposure
Flammability: Highly flammable, vapors form explosive mixtures with air
Environmental risk: Toxic to aquatic life, persistence in soil and water leads to long-term concerns
Routes of exposure: Inhalation, skin contact, eye contact, accidental ingestion
Symbol: Flame, exclamation mark, possible skull and crossbones icons
Risk phrases: Harmful by inhalation and in contact with skin, risk of serious damage to eyes
Main component: 3-Chloro-2-Methylpropene (typically over 98%)
Impurities: May contain traces of stabilizers or manufacturing residues but remains a single-component compound in most laboratory settings
Inhalation: Move to fresh air, watch for signs of breathing difficulty, seek urgent medical attention if symptoms linger
Skin contact: Rinse thoroughly with water for at least 15 minutes, remove contaminated clothing, watch for blistering or burns, medical attention needed for persistent symptoms
Eye contact: Flush eyes gently with water for several minutes, remove contact lenses, seek medical help as damage may progress
Ingestion: Do not induce vomiting, rinse mouth, drink water if conscious, immediate medical care is crucial
Suitable extinguishing media: Dry chemical powder, carbon dioxide, foam, avoid using water jets directly as the chemical floats on water and may spread flames
Hazardous combustion products: Releases hydrogen chloride, phosgene, and other toxic vapors upon burning
Firefighting procedures: Wear self-contained breathing apparatus, full protective gear, cool exposed containers with water spray
Special hazards: Explosive vapor-air mixtures possible in confined or poorly ventilated areas
Personal precautions: Evacuate area, avoid breathing vapors, ensure adequate ventilation, use chemical splash goggles and gloves
Containment methods: Dike spills with inert material like sand or earth, prevent entry into drains and waterways
Clean-up techniques: Use non-sparking tools, absorb with inert material, collect in closed, labeled containers for disposal, thoroughly ventilate area after clean-up
Safe handling: Use only in well-ventilated spaces, ground containers during transfer, keep away from heat, sparks, open flames
Storage conditions: Store in tightly sealed metal drums or glass bottles, out of direct sunlight, away from incompatible chemicals like strong oxidizers and acids, keep in a cool dry place
Labeling: Clearly mark all containers with hazard warnings, use secondary containment in storage areas
Ventilation: Use fume hoods or explosion-proof exhaust systems in areas handling large quantities
Respiratory protection: Approved organic vapor respirators for spills or large scale use
Skin protection: Chemical-resistant gloves, flame-retardant lab coats, boots
Eye protection: Chemical splash goggles, face shield if splashing possible
Monitoring: Regular air quality checks, routine inspection of ventilation equipment
Physical state: Clear, slightly yellow liquid
Boiling point: Approximately 68°C
Melting point: Below -100°C, liquid at standard room temperature
Vapor pressure: Moderate at room temperature, leads to vapor formation and inhalation risk
Flash point: Around -15°C, easily ignited by static discharge or spark
Solubility: Poor in water, mixes with most organic solvents
Odor: Strong, irritating, recognizable even at low concentrations
Chemical stability: Unstable when exposed to heat, light, or air for extended periods
Incompatible materials: Strong oxidizers, acids, alkali metals
Reactive hazards: May form explosive mixtures with air, may release toxic chlorine-containing gases on decomposition
Polymerization: Possible, especially if stabilizers are absent or concentration is high
Routes of exposure: Inhalation, skin contact, accidental swallowing
Immediate effects: Burns, respiratory irritation, coughing, dizziness
Chronic effects: Prolonged exposure has led to reports of central nervous system depression, potential risk of developing cancers in animal studies
Sensitization: No clear data on long-term sensitization, but repeated exposure may enhance skin and mucous membrane sensitivity
Aquatic toxicity: Harmful or toxic to aquatic organisms, possible risk of bioaccumulation
Environmental fate: Persistent in soil and water, limited biodegradability, may contaminate groundwater if not contained properly
Air volatility: Evaporates quickly, contributing to vapor phase pollution in indoor and outdoor settings
Disposal methods: Incinerate with proper pollution controls, avoid landfill, ensure all waste packaging is properly labeled as hazardous
Local guidelines: Follow regional and national hazardous waste disposal regulations, use authorized hazardous waste contractors
Reuse or recycling: Not typically feasible due to toxicity and contamination risks, best handled as hazardous waste
UN Number: Classified under hazardous goods codes for organic solvents
Proper shipping name: Chlorinated hydrocarbon, flammable liquid
Transport risk: High, due to flammability and toxicity, strict shipping regulations for road, rail, air, and sea
Labeling requirement: Flammable liquid and toxic substance markings, leak-proof and pressure-tested containers essential
Chemical control laws: Often included in regional lists of substances requiring tracking, handling permits, or limited access
Worker safety: Employers must provide extensive safety training, written handling procedures, access to emergency equipment
Community right-to-know: Subject to local reporting laws due to environmental and human health risks
Export and import rules: May require special permits, notification of destination authorities, tracking from shipment to delivery
