Chemical Name: Tripropylamine
Synonyms: N,N-Dipropylpropan-1-amine
CAS Number: 102-69-2
Molecular Formula: C9H21N
Appearance: Colorless to pale yellow liquid with a strong, amine-like odor
Odor: Distinctly amine-like, hard to forget if encountered in close quarters
Uses: Serves as a corrosion inhibitor, catalyst, pharmaceutical intermediate, part of the story for manufacturing, industrial and research labs, and chemical synthesis
GHS Classification: Flammable liquid (Category 3), Acute toxicity, Skin irritant, Eye irritant, Specific target organ toxicity
Signal Word: Warning
Hazard Statements: Flammable liquid and vapor, causes skin irritation, causes serious eye irritation, may cause respiratory irritation
Precautionary Statements: Avoid breathing vapor or mist, keep away from heat, sparks, open flames, avoid contact with skin and eyes, wash hands thoroughly after handling
Potential Health Effects: Inhalation brings irritation to the nose or throat, while skin exposure leaves burning sensations. Eyes react harshly, with watering and pain. Extended contact may trigger headaches, nausea, or dizziness.
Main Ingredient: Tripropylamine
Purity: Generally 99% or greater
Impurities: Lower amines or similar organic compounds may be trace byproducts, but commercial Tripropylamine in industrial and lab supply channels usually presents as a single chemical species.
Inhalation: Remove to fresh air, keep the person at rest, monitor for persistent cough or breathing difficulties, get medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, rinse affected skin thoroughly with plenty of water and mild soap, watch for persistent irritation; see medical team if redness or pain doesn't subside
Eye Contact: Rinse eyes carefully with plenty of water for at least fifteen minutes, occasionally lifting eyelids; don't rub the eyes; seek professional medical help, as lasting exposure may damage tissue
Ingestion: Rinse mouth, do not induce vomiting, get immediate medical attention, and provide medical personnel with the name of the chemical if possible
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: Avoid using a strong water jet, since it may spread the fire
Hazards from Combustion: Combustion releases toxic fumes, including nitrogen oxides and carbon monoxide; lingering gases pose inhalation hazards for responders
Advice for Firefighters: Full protective gear and self-contained breathing apparatus are recommended, as smoke and fumes may irritate or incapacitate responders; cool exposed containers to prevent rupture, and keep runoff contained to avoid environmental harm
Personal Protection: Wear gloves resistant to chemicals, eye protection, and if vapor concentrations rise, appropriate respirators
Environmental Precautions: Prevent runoff from entering sewers, surface water, or soil—Tripropylamine’s volatility and solubility can quickly spread contamination
Cleanup Methods: Absorb spill with inert material such as sand or vermiculite, shovel waste into containers for disposal, ventilate the area well, and decontaminate surfaces with suitable cleaning agents
Incident Reporting: Promptly inform safety teams, as exposure or even contained releases may need internal incident tracking or local authority notification if significant
Safe Handling: Use in a well-ventilated place, ground and bond containers to prevent static discharge, keep away from open flames or ignition sources, avoid skin and eye contact, and do not breathe vapors
Safe Storage: Store in tightly sealed containers, keep in a cool, dry area away from incompatible substances like strong oxidizers, acids, and halogens, prevent build-up of static charge by grounding storage tanks, and ensure storage area features good fire suppression systems
Incompatibilities: Strong oxidizing agents, acids, moisture, and halogenated compounds may cause dangerous reactions or degrade product quality
Occupational Exposure Limits: No established national occupational exposure limits in many countries, but prudent ventilation and exposure minimization apply
Engineering Controls: Fume hoods or local exhaust recommended, especially during transfer or open handling
Personal Protective Equipment: Impermeable gloves (nitrile or neoprene), splash proof safety goggles or face shields, protective lab coats or chemical aprons, appropriate footwear
Respiratory Protection: Respirators may be needed if airborne concentrations reach irritation threshold, especially during spill response or bulk material transfer
Physical State: Liquid
Color: Colorless to yellowish
Odor: Strong, ammonia-like
Melting Point: Not easily measured due to volatility, but well below ambient conditions
Boiling Point: Around 158°C
Density: About 0.77 g/cm³
Solubility: Miscible with many organic solvents, limited solubility in water
Vapor Pressure: Significantly volatile above room temp, contributing both odor and flammability concerns
Flash Point: Near 38°C, easily reached in warm storage or in poorly ventilated areas
Viscosity: Low, flows readily
pH: Strongly basic in aqueous environments
Chemical Stability: Stable under recommended storage conditions, but can degrade in presence of moisture, acids, or oxidizers
Reactivity: Reacts vigorously with strong acids and oxidizing chemicals, can trigger fire or toxic fume production
Hazardous Decomposition Products: When heated or under combustion, releases nitrogen oxides, carbon monoxide, carbon dioxide, along with possible amine byproducts
Polymerization: Product does not undergo hazardous polymerization under normal conditions
Acute Exposure Symptoms: Eye, skin, and respiratory tract irritant, with potential for chemical burns upon sustained contact; ingestion causes gastrointestinal distress
Chronic Exposure Risks: Repeated contact may defat skin, cause dermatitis, or trigger cumulative respiratory irritation
Oral and Inhalation Toxicity: Animal studies indicate moderate acute toxicity, above thresholds typically encountered in routine industrial work, but ample caution limits risk
Carcinogenicity: No classification as carcinogen by major regulatory agencies
Other Potential Effects: Sensitization not commonly reported, but prudent exposure reduction always helps avoid unforeseen effects
Aquatic Toxicity: Moderately toxic to aquatic life in concentrated form, with potential for rapid spread in water due to volatility and solubility; spills can result in localized fish kill or aquatic imbalance
Mobility: High volatility leads to ready atmospheric spread; soil binding is modest, hence runoff easily transfers chemical from spills
Persistence and Degradability: Subject to biodegradation, though persistence rises in large-volume spills or poorly aerated environments
Bioaccumulation: Limited propensity for bioaccumulation based on current environmental monitoring studies, but periodic scrutiny recommended near manufacturing or discharge locations
Product Disposal: Incineration in approved chemical waste facility, never down the drain, in regular trash, or in public landfills
Container Disposal: Triple rinse and puncture before disposal as hazardous waste, following local guidance
Regulatory Status: Treated as hazardous waste under many regional, national, and local guidelines, triggering special tracking, reporting, or transport restrictions
Waste Minimization: Recycle or recover unused product where possible to minimize environmental burden
UN Number: UN 2733
Proper Shipping Name: Tripropylamine
Transport Hazard Class: Class 3 (Flammable Liquid)
Packing Group: III
Label Requirements: Flammable liquid marking is mandatory
Special Provisions: Secure upright containers, segregate from foodstuffs, and document transport per applicable international or domestic standards
Chemical Inventories: Tripropylamine appears on the US TSCA, Canadian DSL, EU REACH, and most major chemical inventories
OSHA Status: Recognized hazard due to flammability and acute irritant effects
SARA Title III: May be subject to reporting in case of accidental releases
Labeling: GHS hazard labeling required wherever supplied or used
