Chemical Name: N-Benzyl-N-Ethylaniline
Common Synonyms: N-Benzyl-N-Ethylbenzenamine
Molecular Formula: C15H17N
CAS Number: 92-59-1
Appearance: Colorless to pale yellow liquid, aromatic odor
Major Use: Intermediate in organic synthesis, dye industries, research labs
Hazard Class: Irritant to eyes and skin, possible central nervous system depressant
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Symptoms: Eye and skin irritation, headache, nausea with inhalation, potential drowsiness
Users should watch for dermatitis, coughing, sore throat, or dizziness during unprotected handling
Flammable liquid; vapors may form explosive mixtures with air
If combusted, may produce nitrogen oxides and toxic fumes
Chemical: N-Benzyl-N-Ethylaniline
Concentration: Typically supplied in pure or near-pure form
Impurities: Trace amounts of related anilines or benzene derivatives possible depending on synthesis route
Eye Contact: Rinse gently with plenty of water for 15 minutes, remove contact lenses if present
Skin Contact: Wash immediately with soap and flowing water, remove contaminated clothing
Inhalation: Move out to fresh air, keep airway clear, provide oxygen if breathing is troubled
Ingestion: Rinse mouth thoroughly, avoid inducing vomiting, seek medical attention quickly
For any case, make sure an emergency responder knows the substance involved
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide, avoid strong water jets
Hazards: Releases toxic nitrogen oxides and carbon monoxide on combustion, may emit dense black smoke
Special Protective Equipment: Firefighters need self-contained breathing apparatus, full protective gear
Runoff from fire control could pollute waterways; prevent spillage into drains
Depending on storage method, containers may rupture in fire due to heat expansion
Personal Precautions: Wear chemical-resistant gloves, goggles, and suitable protective clothing
Environmental Protection: Keep out of soil, surface water, drains; substance can harm aquatic life
Clean Up: Absorb spillage with inert materials like vermiculite or sand, collect in secure containers
Ventilate area thoroughly, dispose spilled waste as hazardous; avoid use of unprotected vacuum lines
All contaminated tools and surfaces must be washed—preferably with industrial cleaning agents
Handling: Work in well-ventilated areas or use fume hoods, avoid skin and eye contact, don’t eat near chemicals
Always keep containers tightly sealed; utilize non-sparking tools when dispensing
Use personal protective equipment to minimize exposure during transfer
Storage: Store in a cool, dry, well-ventilated place away from ignition sources
Keep away from oxidizers, acids, or bases; store in clearly labeled chemical-resistant containers
Engineering Controls: Local exhaust ventilation, lab fume hoods, sealed transfer systems when possible
Eye Protection: Chemical splash goggles or full face shield
Hand Protection: Solvent-resistant gloves such as nitrile or neoprene
Skin Protection: Long sleeves, lab coat, apron when risk of splashes exists
Respiratory Protection: Use NIOSH-approved respirators if airborne concentrations approach or exceed limits
Hygiene Measures: Wash hands before breaks, after using the compound, and before eating or drinking
Physical State: Liquid at room temperature
Color: Colorless to faint yellow
Odor: Aromatic, strong
Boiling Point: About 299°C
Melting Point: -32°C
Solubility: Not soluble in water; soluble in organic solvents like acetone, ether
Density: Approximately 0.98 g/cm³
Vapor Pressure: Low under ambient conditions
Flash Point: Around 135°C
Stability: Stable under proper storage; avoids heat, sparks, and open flame
Incompatibilities: Strong oxidizers, acids, alkalis, halogens
Decomposition: Yields nitrogen oxides, carbon monoxide, and irritating organic vapors if burned or exposed to strong acids
May undergo hazardous polymerization or decomposition in extreme conditions
Toxicity: May irritate eyes, skin, and respiratory tract; ingestion can cause gastrointestinal upset and central nervous distress
Chronic Exposure: Prolonged or repeated contact may cause dermatitis; sustained vapor exposure may impact liver or kidneys
Carcinogenicity: Not classified as carcinogenic by IARC or major regulatory bodies as of recent reviews
Sensitization: Data limited, but anilines sometimes cause skin sensitization over time
LD50 Values: Based on similar anilines, acute oral LD50 in rodents ranges from 1000 to 2000 mg/kg; exact values for this compound are less documented
Persistence: Likely degrades slowly in the environment; not readily biodegradable
Bioaccumulation: Moderate potential based on structure; data limited
Toxicity to Aquatic Life: Expected to be toxic in higher concentrations; could disrupt aquatic environments if spilled
Mobility: Largely insoluble in water, binds to organic material in soil, spills will linger unless actively removed
Disposal and emissions should be minimized to prevent long-term ecological impacts
Disposal Method: Treat as hazardous chemical waste; incinerate in approved facility or use certified chemical disposal services
Contaminated Packaging: Dispose as hazardous waste, rinse thoroughly only if regulations permit; label containers to prevent mishandling
Do not pour into drains, sinks, or general rubbish; prevent runoff into environment
Consult local and national regulations for hazardous waste for proper protocols
Shipping Name: N-Benzyl-N-Ethylaniline, chemical freight
Hazard Class: Classified as a flammable liquid under many transport codes
Packing: Use leak-proof, chemical-resistant containers with clear hazard labels
Transport in climate-controlled vehicles when available; keep away from strong oxidizers and combustible materials during transport
Spill response kits and fire suppression systems should be available during large shipments
Regulation: Listed as hazardous under chemical safety regulations in major industrial countries
Worker Safety: Occupational exposure standards may be set in some regions; check with local authorities
Labeling: Requires clear hazard warnings and risk phrases as per GHS or local standards
Environmental Release: Reportable quantities for environmental releases where required by national or regional agencies
Users and handlers must keep current with changing safety and transport rules to stay in compliance
