Name: 2,4-Dichloronitrobenzene Chemical Formula: C6H3Cl2NO2 Common Use: Manufacture of dyes, pesticides, pharmaceuticals Physical Appearance: If you've tried handling it, you’ll find a yellow crystalline solid. CAS Number: 611-06-3
Classification: Acute toxicity by inhalation and ingestion, strong eye and skin irritant Risk Phrases: Harmful if swallowed, toxic by inhalation, causes burns, danger to aquatic life Signal Word: Danger Hazard Statements: Damages skin, eyes, and respiratory tract upon exposure Symptoms From Exposure: If you breathe it in, expect coughing, irritation; touch it, experience burning
Active Component: 2,4-Dichloronitrobenzene, usually at high purity Contaminants: Possible traces of monochloronitrobenzenes, polychloronitrobenzenes depending on the synthesis
Inhalation: Move to open air and seek immediate medical attention if symptoms appear Skin Contact: Remove contaminated clothing, rinse with water for a prolonged period Eye Contact: Rinse cautiously for several minutes with clean water, make sure to get medical help Ingestion: If swallowed, don’t try home remedies; head to the hospital—medical teams have the antidotes
Extinguishing Media: Use dry chemical, carbon dioxide, or foam; water may spread the chemical Hazards During Fire: Decomposition produces toxic gases like hydrogen chloride, nitrous oxides Personal Protective Equipment: Self-contained breathing apparatus, full protective gear is key
Personal Protection: Put on gloves, eye protection, don’t let the dust get on your skin or clothes Containment: Prevent spread of dust, isolate the hazardous area Cleanup: Use inert absorbent material, gather carefully and place in sealed containers Environment Precautions: Avoid runoff into drains or soil because harm to water organisms is real
Safe Handling: Work in a fume hood, wear protective gloves, avoid skin contact as much as possible Storage: Store in tightly closed containers, cool and well-ventilated place; keep separate from strong acids and bases Incompatibilities: Strong oxidizers, reducing agents
Engineering Controls: Fume hoods or local exhaust; standing at an open bench can be risky Personal Protection: Chemical-resistant gloves, splash goggles, lab coat, face shield if splashing possible Respiratory Protection: If dust or vapors become airborne, use NIOSH-approved respirator Hygiene: Wash hands thoroughly after use, don’t eat or drink near the work area
Physical State: Yellow crystalline solid Melting Point: Near 53°C Boiling Point: Around 285°C Solubility: Practically insoluble in water but dissolves in organic solvents like ethanol or acetone Odor: Mild, chemical-like; not overpowering but noticeable Vapor Pressure: Low under normal temperatures
Chemical Stability: Stable under ordinary conditions if kept dry and away from incompatible materials Hazardous Reactions: Generates toxic gases with strong reducing or oxidizing agents Conditions to Avoid: High heat, open flame, exposure to light for long periods
Routes of Exposure: Absorbed by inhalation, ingestion, skin, and eyes Toxic Effects: Prolonged contact triggers skin burns, eye lesions, and respiratory irritation Symptoms: Headache, nausea, dizziness, breathing trouble after exposure Chronic Effects: Long-term contact linked to organ and blood disorders; animal studies reveal toxicity
Toxicity to Aquatic Life: Substance damages aquatic organisms, persists in water and sediments Persistence and Degradation: Slow breakdown in soil and water; has the potential to bioaccumulate Environmental Mobility: Hardly moves in soil, roots itself in sediments
Residual Handling: Gather waste and leftovers, send to hazardous chemical disposal facility Incineration: Consider incineration with emission control; never pour down the drain Container Precautions: Empty containers still hold risk—triple rinse or treat as hazardous
UN Number: Classified as hazardous for transport Packaging: Leak-proof packaging, clear hazard label required Handling Guidelines: Keep away from food, animal feed, and public spaces during shipment
Occupational Exposure Limits: Many countries set strict limits—check local laws Environmental Release: Reporting required if large spills or releases take place Worker Protection: Labor safety regulations demand education on handling and personal protection
