Common Uses: Dye intermediates, research reagents, specialty chemical synthesis
Molecular Formula: C16H19N
Physical Appearance: Oily liquid, pale yellow to brown
Odor: Amine-like, strong and pungent
CAS Number: 86-15-5
Acute Effects: Eye and skin irritation, respiratory discomfort if inhaled, headaches, potential for dizziness
Chronic Effects: Persistent exposure linked to liver and kidney changes in laboratory studies
Flammability: Combustible liquid, may emit toxic fumes upon burning
Environmental Hazard: Potential toxic effects in aquatic systems
Signal Word: Warning
Main Ingredient: N,N-Diethyl-1-Naphthylamine
Concentration: Typically over 98% in technical grades
Impurities: Byproducts from synthesis and secondary amines, can influence safety profile
Inhalation: Remove to fresh air, support breathing, seek immediate medical attention if symptoms persist
Skin Contact: Wash immediately with water and soap, remove contaminated clothing
Eye Contact: Flush eyes with water for several minutes, consult physician quickly
Ingestion: Rinse mouth, do not induce vomiting, get medical help at once
Symptoms to Watch: Breathing difficulties, lasting irritation, headaches
Suitable Extinguishing Media: Carbon dioxide, dry powder, foam
Fire Hazards: Burns with toxic fume release including nitrogen oxides, possible risk of flashback
Protective Equipment: Full protective suit, self-contained breathing apparatus
Specific Dangers: Vapors heavier than air, may travel across ground and ignite at distant points
Advice for Firefighters: Keep containers cool with water spray, avoid entry of runoff to water courses
Personal Precautions: Appropriate gloves, goggles, avoid skin and eye exposure
Environmental Precautions: Prevent spillage from entering drains and waterways
Cleanup Methods: Absorb with inert material like sand or vermiculite, bag securely for disposal
Ventilation: Use in well-ventilated area to avoid inhaling vapors
Handling Precautions: Avoid breathing vapors, prevent contact with eyes and skin, use proper ventilation
Storage Conditions: Store in tightly sealed containers, keep cool and dry, out of sunlight
Compatibility: Keep away from acids, oxidizing agents, open flames
Storage Facilities: Use chemical-resistant shelves and spill containment trays
Engineering Controls: Use chemical fume hoods or extractor fans
Personal Protective Equipment: Chemical splash goggles, neoprene gloves, lab coat
Respiratory Protection: Respirator with organic vapor cartridge for significant airborne concentrations
Hygiene Measures: Wash hands after use, don’t eat or drink in area of use
State: Liquid
Boiling Point: Approximately 302°C
Melting Point: Below ambient room temperature, remains liquid in most working environments
Solubility: Low solubility in water, mixes with most organic solvents
Vapor Pressure: Low at room temperature
Density: About 1.0 g/cm³
Flash Point: Near 150°C, risky if heated without controls
Odor Threshold: Noticeable at low ppm levels, pungent odor contributes to early detection in case of spills
Chemical Stability: Stable under recommended handling and storage, breaks down if exposed to strong acids and oxidizers
Hazardous Reactions: May react exothermically with strong oxidizers or acids, releases toxic vapors under fire
Decomposition Products: Nitrogen oxides, carbon monoxide, various aromatic amines
Incompatibilities: Strong acids, oxidizing chemicals
Acute Toxicity: Can cause irritation to skin, eyes, and respiratory system
Chronic Toxicity: Laboratory animals developed subtle organ damage after repeated exposure
Routes of Exposure: Inhalation, skin absorption, ingestion
Long-term Risks: Possible link to liver and kidney changes
Carcinogenicity: No major agencies have classified as a proven human carcinogen, though structurally related compounds demand caution
Fate in Environment: Low mobility in soil, tends to persist without rapid breakdown
Aquatic Toxicity: Demonstrated toxic effects on fish and invertebrates at moderate concentrations
Bioaccumulation Potential: Possibility of accumulation in aquatic organisms over time
Degradability: Slow in natural water, potential threat with chronic low-level release
Waste Treatment: Burn in licensed chemical incinerator with afterburner and scrubber
Contaminated Packaging: Empty containers can retain product residue, handle as hazardous chemical waste
Legal Disposal: Rely on registered hazardous waste handlers, avoid dumping into drains, soil, or waterways
UN Shipping Name: Classified as hazardous material under chemical shipping regulations
Packing Requirements: Leak-proof, chemical-resistant containers
Transport Hazards: Keep away from food, do not transport with strong acids or oxidizers
Recommended Labelling: Flammable liquid, toxic substance advisory labels
Environmental Regulations: Controlled use and disposal under local environmental protection acts
Workplace Regulations: Subject to occupational exposure limits in several countries, check national chemical safety notifications
Restrictions: Use often limited or registered due to environmental persistence and toxicity concerns
Reporting Requirements: Any major spill or release may require notification to local authorities
