Chemical name: Di-N-Pentylamine
Synonyms: N,N-Dipentylamine
Chemical formula: C10H23N
Common uses: Organic synthesis, intermediate for agrochemicals, pharmaceuticals
Physical description: Colorless to pale yellow liquid; distinct amine odor
Hazard class: Flammable liquid and vapor
Health risks: Harmful if inhaled, swallowed, or absorbed through skin; can cause irritation to eyes, skin, and respiratory system
Environmental risks: Toxic to aquatic life; potential for bioaccumulation
Critical dangers: Vapors can form explosive mixtures with air; rapid combustion possible in confined spaces
GHS signal word: Warning
GHS pictograms: Flame, exclamation mark, environment (for aquatic hazard)
Main component: Di-N-Pentylamine, approximately 98% or higher purity
Impurities: Trace amounts of related amine compounds; specific types depend on synthesis route
Additives: None listed
CAS number: 2050-92-2
Eye contact: Flush eyes with clean water for at least 15 minutes; seek medical attention if irritation continues
Skin contact: Remove any contaminated clothing, wash exposed area with plenty of soap and water; pay attention to lingering irritation or rash
Inhalation: Move the person to fresh air, keep comfortable; get medical help if there are symptoms such as coughing or shortness of breath
Ingestion: Rinse mouth, never give anything by mouth to an unconscious person; medical evaluation recommended quickly for significant ingestion
Symptoms to watch: Burning sensation, headaches, nausea, throat irritation, dizziness
Suitable extinguishing media: Dry chemical powder, alcohol-resistant foam, carbon dioxide
Unsuitable media: Direct use of water jets (as it can spread the fire)
Hazards: Releases toxic fumes such as nitrogen oxides, carbon monoxide during combustion
Protective measures: Wear self-contained breathing apparatus and protective clothing; avoid inhalation of vapors; keep away from ignition sources
Special advice: Cool fire-exposed containers with water spray to prevent bursting
Personal precautions: Avoid skin and eye contact; use appropriate personal protective equipment
Environmental precautions: Prevent run-off into soil, sewers, waterways; report significant spills to local authorities
Cleaning methods: Use inert absorbent materials such as sand or vermiculite; transfer residue to well-labeled containers for disposal; ventilate affected area thoroughly
Spill size consideration: Small spills can be wiped up with absorbent towels, larger spills demand mechanical collection and area isolation
Handling: Keep away from open flames, hot surfaces, and sparks; use in well-ventilated areas with equipment designed to protect workers
Avoid contact: Direct handling without gloves can lead to skin irritation; vapor inhalation can irritate mucous membranes
Storage: Store in cool, dry space in tightly sealed containers; separate from oxidizers, acids, and ignition sources; make sure storage area is equipped with spill containment code
Precautions for containers: Store containers upright with correct labeling
Engineering controls: Local exhaust ventilation, fume hoods, explosion-proof electrical equipment
Personal protection: Chemical-resistant gloves (nitrile or neoprene), splash goggles, laboratory coats; for larger volumes or risk of splash, a face shield and chemical boots make sense
Respiratory protection: Cartridge respirator if there is a risk of inhaling vapors at above-recommended limits
Hygiene: Wash hands before breaks and after handling; no eating or drinking in work area
Appearance: Colorless to pale yellow liquid
Odor: Strong, amine-like
Boiling point: Around 207-208°C
Melting point: Estimated below room temperature
Vapor pressure: Low to moderate at ambient, increases with heat
Solubility: Limited in water, freely mixes with many organic solvents
Densities: Slightly lighter than water
Flash point: Estimated near 86°C (closed cup)
Chemical stability: Stable at room temperature and normal storage conditions
Incompatible materials: Strong oxidizers, acids, acyl halides
Potential reactions: Can form flammable or explosive vapor-air mixtures; risk of violent reaction with oxidizing agents
Hazardous decomposition: Ammonia, nitrogen oxides, carbon monoxide under fire or extreme heat
Acute toxicity: Oral LD50 in rats ranges between 800-1600 mg/kg
Short-term exposure: Main risks involve burns to eyes, mucous membrane irritation, possible central nervous system effects like dizziness or headaches with high vapor concentrations
Long-term exposure: May cause dermatitis with chronic skin contact; insufficient data to confirm carcinogenicity in humans
Sensitization: Rare, but possible in persons with chemical sensitivities
Routes of entry: Inhalation, ingestion, dermal absorption
Aquatic toxicity: Harmful to aquatic organisms, can cause long-term adverse effects in aquatic environments
Persistence and degradability: Limited data; likely to persist if spilled in large quantities
Bioaccumulation potential: Some evidence suggests risk of buildup in aquatic species
Mobility: Spills spread quickly on water surfaces; partial solubility increases risk of groundwater contamination if large spills reach soil
Waste treatment: Must be treated as hazardous waste; incineration in approved facility recommended
Container disposal: Triple rinse, then send to facility equipped to handle chemical residues
Do not: Pour into surface water, sewer systems, or landfills not permitted to handle chemical waste
Recommendations: Follow local and federal rules for chemical disposal; keep thorough records
UN number: Not always assigned, requires confirmation with current agreements
Hazard class: 3 (Flammable liquids)
Packing group: II (moderate danger)
Labeling: Flammable, irritant
Shipping considerations: Use proper leak-proof drums, inform carriers of hazard status, document contents for emergency responders
Transport regulations: Subject to international, national, and local regulations for chemical shipments
Chemical inventory status: Listed or regulated in several national inventories—review current status before use in new jurisdiction
Worker safety: Subject to occupational exposure limits set by local authorities
Environmental release: Spills must be reported to agencies as required
Labeling requirements: GHS standard pictograms, hazard and precautionary statements
Restrictions: Certain uses or disposal methods restricted in some countries for environmental or worker protection
