Composition / Information on Ingredients

Chemical Name: Tripentylamine
Concentration: >98%
CAS Number: 622-26-4
Impurities and Stabilizing Additives: No significant impurities known; trace amounts of related amines possible from synthesis

First Aid Measures

Inhalation: Move person to fresh air, keep at rest, seek medical attention if symptoms develop
Skin Contact: Immediately wash skin with mild soap and plenty of water, remove contaminated clothing, get medical aid if irritation persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical advice
Ingestion: Rinse mouth, do not induce vomiting, get medical aid if you feel unwell

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Direct water jet
Specific Hazards: Emits toxic fumes under fire conditions (nitrogen oxides, carbon monoxide, carbon dioxide)
Protective Equipment: Firefighters need self-contained breathing apparatus, full protective gear
Special Procedures: Cool exposed containers with water spray to prevent bursting, contain runoff to prevent environmental contamination

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, use personal protective equipment including gloves and goggles, ensure adequate ventilation
Environmental Precautions: Prevent entry into sewers or waterways, contain spill with sand or non-combustible absorbent
Cleanup Methods: Collect spillage with absorbent material, dispose according to local regulations, wash spill area with water and detergent, ventilate the area after cleanup

Handling and Storage

Handling: Handle in a well-ventilated area, avoid inhalation and direct contact with skin or eyes, keep away from ignition sources, use non-sparking tools, ground and bond containers
Storage: Store in tightly closed containers in a cool, dry, and well-ventilated place, keep away from incompatible materials like strong oxidizing agents and acids, segregate from food and beverages, keep out of reach of children

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established values for Tripentylamine, limit exposure as recommended for general organic amines
Engineering Controls: Use in well-ventilated areas, fume hoods recommended for laboratory use, local exhaust ventilation for industrial-scale use
Personal Protection: Wear chemically resistant gloves (e.g., nitrile), safety goggles or face shield, long-sleeved clothing, suitable respirator in case of insufficient ventilation
Hygiene Measures: Wash hands and face after handling, remove contaminated clothing and wash before reuse, avoid eating, drinking, or smoking during use

Physical and Chemical Properties

Appearance: Colorless to pale yellow oily liquid

Melting Point: -50°C (approximate)
Boiling Point: 289-295°C (estimated)
Flash Point: 110°C (closed cup, estimated)
Autoignition Temperature: Not established (similar amines: 250-300°C)
Explosive Limits: Not established
Vapor Pressure: Very low at 20°C
Solubility: Insoluble in water, soluble in organic solvents (e.g., ethanol, ether)
Relative Density: 0.81 (approximate)
Viscosity: Not determined

Stability and Reactivity

Chemical Stability: Stable under ordinary conditions of use and storage
Reactivity: Reacts with strong oxidizing agents, reacts violently with acids
Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, carbon dioxide, other toxic vapors at high temperatures
Polymerization: Not known to occur
Incompatible Materials: Acids, oxidizers, strong halogenating agents

Toxicological Information

Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Harmful if swallowed; data not widely reported, but similar tertiary amines show oral LD50 (rat) around 500-2000 mg/kg
Skin Corrosion/Irritation: Causes irritation, redness, discomfort
Eye Damage/Irritation: Causes significant irritation, redness, tearing
Respiratory Sensitization: May cause coughing and respiratory irritation if vapors are inhaled
Chronic Toxicity: Prolonged or repeated exposure may dry or crack skin, cause allergic skin or respiratory reactions in susceptible individuals
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No data available for Tripentylamine itself, not listed by IARC, NTP, or OSHA

Ecological Information

Ecotoxicity: Limited data; similar amines toxic to aquatic life, especially fish and invertebrates; avoid release to the environment
Persistence and Degradability: Expected to be biodegradable slowly; amines may persist under certain conditions
Bioaccumulation Potential: Moderate, due to low water solubility and lipophilicity
Mobility in Soil: Expected to adsorb to soil particles and have low mobility
Other Adverse Effects: No significant ozone depletion or global warming potential

Disposal Considerations

Waste Treatment Methods: Dispose of through licensed chemical waste contractor, following local laws and regulations
Product Disposal: Collect in sealed containers, label appropriately, do not discharge into drains or the environment
Contaminated Packaging: Empty containers retain product residue, triple rinse before recycling or disposal, treat as hazardous

Transport Information
