Chemical Name: 2-Ethoxyaniline
CAS Number: 94-70-2
Percent Composition: >98%
Impurities: Minimal, mainly related aniline derivatives
Inhalation: Remove person to fresh air, keep comfortable, provide oxygen if breathing is difficult, seek medical attention
Skin Contact: Remove contaminated clothing, rinse skin carefully with water for multiple minutes, seek medical assistance for irritation or allergic reaction
Eye Contact: Rinse eyes with water for at least 15 minutes, remove contact lenses if easy, continue rinsing, obtain urgent medical evaluation
Ingestion: Rinse mouth, do not induce vomiting, never give anything by mouth to an unconscious individual, seek immediate medical advice
Important Symptoms: Burning, irritation, redness, allergic reactions, respiratory discomfort
Medical Attention: Seek care without delay if symptoms persist or severe exposure occurs
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, water spray (avoid high pressure jets)
Specific Hazards: Combustion produces hazardous gases such as nitrogen oxides, carbon monoxide, and carbon dioxide; vapors may form explosive mixtures with air
Protective Equipment: Firefighters use self-contained breathing apparatus and protective clothing
Firefighting Procedures: Evacuate area, cool exposed containers with water, prevent runoff into sewers, avoid inhalation of combustion products
Personal Precautions: Evacuate area, restrict entry, wear respirator and protective gear
Environmental Precautions: Prevent spillage from reaching waterways, soil, and drains
Containment: Use inert absorptive material such as sand or vermiculite, collect residues in labeled chemical waste containers
Cleanup Methods: Shovel up and place in tight containers for disposal according to regulations; thoroughly ventilate affected area and wash with suitable cleaning agents
Handling: Wear appropriate PPE, use only in well-ventilated areas, avoid inhalation and direct contact with skin and eyes, keep chemical away from combustible materials and open flames
Storage: Store tightly sealed in cool, dry, well-ventilated location, segregate from foodstuffs and incompatible substances such as strong oxidizers and acids, maintain temperature stability, label clearly
Engineering Controls: Use fume hoods, local exhaust ventilation, safety showers, eyewash stations
Personal Protection: Wear chemical-resistant gloves (nitrile), impervious clothing, eye protection with side shields or goggles, NIOSH-approved respirator for airborne concentrations, avoid skin exposure
Exposure Limits: No established OSHA or ACGIH TLV for 2-Ethoxyaniline; minimize exposure due to toxicity
Appearance: Pale yellow to brown liquid
Odor: Faint, aromatic
Melting Point: -13°C
Boiling Point: 224°C
Flash Point: 100°C (closed cup)
Solubility: Moderate in water, miscible with alcohols, ethers
Density: 1.06 g/cm³
Vapor Pressure: Low at ambient temperature
pH: Not applicable (neutral liquid)
Partition Coefficient: n-octanol/water: data limited, expected moderate
Evaporation Rate: Slow
Explosive Limits: Not well defined, handle with standard precautions
Chemical Stability: Remains stable under normal temperatures and pressures
Reactivity: May react with strong oxidizers, acids, acylating agents
Hazardous Reactions: Exothermic with incompatible materials
Decomposition Products: Releases toxic fumes like nitrogen oxides and carbon oxides during thermal decomposition
Conditions to Avoid: Excessive heat, open flame, moisture, incompatible substances
Polymerization: Not likely under recommended handling conditions
Acute Toxicity (Oral): High, LD50 (rat) around 350 mg/kg
Acute Toxicity (Dermal): Harmful
Inhalation: Harmful, causes respiratory tract irritation, headache, cyanosis with high exposures
Skin/Eye Irritation: Produces significant irritation and burns; can sensitize skin after repeated exposure
Chronic Effects: Risk of methemoglobinemia, liver and kidney impairment on prolonged exposure
Carcinogenicity: No classification by major agencies, structurally related to aniline compounds with potential carcinogenic risk
Mutagenicity: Some evidence in cell-based assays but lacking full animal confirmation
Other Effects: May induce allergic skin reactions, hemolytic anemia in sensitive individuals
Toxicity: Harmful to aquatic organisms even at low concentration, acute EC50 (fish) data limited
Persistence and Degradability: Does not degrade rapidly in environment, persistence expected in soil and water if spilled
Bioaccumulative Potential: Moderate, does not rapidly bioaccumulate
Mobility: Moderate mobility in soil with risk to groundwater if large spill occurs
Other Adverse Effects: Toxic for microorganisms engaged in waste treatment, may disrupt biological systems
Disposal Information: Classified as hazardous waste; incinerate under controlled conditions or dispose in licensed chemical landfill following local, regional, and federal guidelines
Contaminated Packaging: Rinse, puncture, and dispose of according to hazardous waste protocols
Precautions: Prevent substance from entering drains or watercourses during disposal, avoid all contact with soil or vegetation
