Concentration: >98%
Impurities: Less than 2% unidentified trace organics
CAS Number: 504-02-9
EC Number: 207-967-1
Inhalation: Move person to fresh air. Keep airways open. Monitor for breathing difficulties. If symptoms persist, get medical attention.
Skin Contact: Remove contaminated clothing. Wash affected area with plenty of soap and water. Seek care for persistent redness or irritation.
Eye Contact: Rinse eyes with gentle stream of water for at least 15 minutes, holding eyelids open. Remove contact lenses if present and easy. Immediate consultation by medical staff recommended for any vision changes.
Ingestion: Rinse mouth immediately. Do not encourage vomiting. Seek immediate medical evaluation.
Most Important Symptoms: Burning sensation, coughing, skin redness, watering eyes, gastric discomfort
Suitable Extinguishing Media: Dry chemical, CO2, alcohol-resistant foam. Do not use water jets, as these spread flames.
Specific Hazards: Vapors may form explosive mixtures with air. Containers can rupture when heated. Risk of toxic nitrogen oxide gases under fire.
Protective Equipment: Wear full protective gear and self-contained breathing apparatus. Stay upwind, use water-spray to cool heated tanks.
Advice for Fire Fighters: Avoid direct contact with leaked material. Eliminate all ignition sources. Watch runoff water for pollution risk.
Unusual Fire/Explosion Hazards: Similar to other light amines, rapid vaporization possible when heated or released under pressure.
Personal Precautions: Isolate area. Evacuate non-essential personnel. Don chemical splash goggles and gloves. Use ventilation.
Methods for Clean-up: Small spills – absorb with inert material and place in labeled chemical waste container. Large spills – dike for later disposal, use explosion-proof equipment.
Environmental Precautions: Keep out of drains, surface water, and soil. Notify local regulations if environment contamination risk.
Decontamination: Wash residue with soap and large volumes of water. Dispose of all cleaning materials as hazardous waste.
Precautions: Use only with adequate ventilation or extraction. Ground all equipment. Avoid sparks, static, and open flames anywhere near containers. Wash thoroughly after handling.
Safe Storage Conditions: Store locked up in a cool, dry, and well-ventilated area made of non-combustible materials. Use tightly sealed containers, resistant to amines. Label storage area for flammable liquids.
Incompatible Materials: Strong oxidizers, acids, acid chlorides, nitrating agents, peroxides—may react violently. Avoid copper, brass, and aluminum equipment that can corrode.
Engineering Controls: Local exhaust ventilation, fume hood, spark-proof electrical tools. Maintain vapor concentrations below exposure limits.
Personal Protection: Chemical splash goggles, lab coat or apron, nitrile or butyl gloves, flame-resistant clothing in bulk transfers. For high vapor, use organic vapor NIOSH/MSHA approved respirator.
Exposure Limits: No official OSHA PEL or ACGIH TLV at publication, but treat with limitations used for similar amines.
Hygiene Measures: Wash after use, remove contaminated clothes, avoid skin contact.
Appearance: Colorless to pale yellow liquid
Odor: Characteristic amine odor, sharp
Boiling Point: 137–139°C (280–282°F)
Melting Point: -12°C (10.4°F)
Flash Point: 32°C (90°F) (closed cup)
Flammability: Flammable
Auto-ignition Temperature: 260°C (500°F)
Vapor Pressure: 7 mmHg at 25°C
Solubility: Miscible with water, ethanol, ether
Density: 0.84 g/cm³ at 20°C
Partition Coefficient (log Kow): 1.32
Viscosity: Not determined
Stability: Stable under normal temperatures and pressures, in recommended containers.
Hazardous Reactions: May react with oxidizers, reducing agents, acids. Incompatible with strong bases leading to heat release.
Decomposition Products: Toxic nitrogen oxides, volatile organic fragments
Polymerization: Hazardous polymerization not anticipated.
Acute Toxicity: LD50 (oral, rat): 350 mg/kg
Routes of Exposure: May enter body by inhalation, ingestion, or skin absorption.
Effects: Burning, headache, dizziness, confusion, respiratory irritation, stomach pain, potential effect on nervous system
Skin Contact: Redness, dryness, blistering possible from repeated exposure
Eye Contact: Severe irritation, tearing, risk of cornea damage on direct splash
Sensitization: No definitive evidence from available data; long-term repeated contact may still cause problems
Chronic Effects: No human data for carcinogenicity, mutagenicity, reproductive impact
Environmental Fate: Expected to biodegrade in soil and water over time. Rapid redistribution in water columns likely, moderate persistence.
Ecotoxicity: Toxic to aquatic life in concentrated spills. LC50 (fish, 96hr): <50 mg/L estimated
Bioaccumulation: Low potential (low partition coefficient)
Mobility: High solubility may lead to runoff; chemical is not expected to adsorb significantly onto soil particles
Other Adverse Effects: Spills rapidly spread odor, can cause local environmental complaints
Waste Disposal: Incinerate in chemical incinerator equipped for amine destruction and scrubbers. Do not pour into drains or sewers. Dispose according to local, national, and regional regulations.
Contaminated Containers: Triple rinse, puncture, and send to licensed chemical waste facilities. Label as hazardous—ensure residues are not present before landfill disposal.
Methods: Collect and contain spillage, seek specialized hazardous waste contractor if unsure about handling.
