Chemical Name: N-Pentylamine
Synonyms: 1-Aminopentane
Molecular Formula: C5H13N
Physical Description: Clear, colorless to slightly yellow liquid with a fishy, ammonia-like odor
Uses: Intermediate for organic synthesis, potential corrosion inhibitor, laboratory reagent
Hazard Classification: Flammable liquid and vapor, acute toxicity (oral, dermal, inhalation), irritant
Pictograms: Flame, exclamation mark
Main Risks: Fire hazard, strong irritation to eyes, skin, and respiratory tract
Environmental Hazards: Harmful to aquatic life due to toxicity and persistence
Component: N-Pentylamine
Concentration: Usually found at or near 100% in pure form
CAS Number: 110-58-7
Inhalation: Move person to fresh air immediately. If breathing is difficult, supply oxygen if possible. Call a physician if symptoms persist.
Skin Contact: Remove contaminated clothing. Rinse skin thoroughly with water for many minutes. Seek medical attention if irritation continues.
Eye Contact: Flush eyes gently with plenty of water for at least 15 minutes, lifting eyelids occasionally. Seek immediate medical help.
Ingestion: Do not induce vomiting. Rinse mouth with water if conscious. Call poison control or medical help right away.
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide
Unsuitable Media: Water jets can spread fire
Hazardous Combustion Products: Emits toxic gases like nitrogen oxides and carbon monoxide upon combustion
Advice for Firefighters: Wear self-contained breathing apparatus and protective gear. Cool surrounding containers with water spray to prevent pressure build-up or explosion.
Flash Point: Around 44°C (reports vary somewhat)
Personal Precautions: Wear gloves, goggles, face shield, and respirator if required to avoid contact and inhalation
Environmental Cautions: Prevent runoff to drains, soil, or water bodies due to toxicity
Cleanup Steps: Ventilate area, absorb with inert material like sand or earth, scoop up, and place in a safe waste container. Clean residues with soap and water.
Safe Handling: Work in a ventilated setting or fume hood, minimize vapor formation, avoid contact with skin and eyes, keep away from heat and ignition sources
Storage Conditions: Store in tightly closed containers, keep in cool, dry, well-ventilated spaces, away from oxidizing agents, acids, and ignition sources
Other Precautions: Ground and bond containers during transfer to prevent static discharge. Train staff on spill and exposure response.
Exposure Limits: No established occupational exposure values in most jurisdictions, but treat as hazardous
Personal Protective Equipment: Chemical-resistant gloves (nitrile), safety goggles, face shield, flame-retardant lab coat, use a respirator with organic vapor cartridge in high vapor or spill areas
Engineering Controls: Chemical fume hood or local exhaust ventilation strongly recommended. Emergency eye wash and safety shower facilities should be within reach.
Appearance: Clear to lightly yellow liquid
Odor: Pungent, amine, fishy
Boiling Point: About 104°C
Melting Point: -60°C
Solubility in Water: Miscible
Vapor Pressure: Moderate at room temperature
Density: Roughly 0.77 g/cm³
pH: Strongly alkaline in solution
Flammability: Highly flammable liquid with a low flash point
Vapor Density: Heavier than air
Stability: Stable under recommended conditions, sensitive to air and light if stored improperly
Reactivity: Reacts with acids, oxidizers, strong reducing agents
Hazardous Reactions: Can produce heat, strong fumes, or even fire upon contact with reactive chemicals
Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, carbon dioxide released in fire or high heat
Acute Toxicity: Can cause headache, dizziness, nausea, respiratory discomfort, skin burns, eye damage
Chronic Exposure: May sensitize or irritate respiratory tract or skin with repeated or prolonged contact
Routes of Exposure: Inhalation, dermal, and oral absorption
Immediate Effects: Burning sensation, cough, tearing, inflammation of skin or mucous membranes
Other Risks: Though not widely reported as a carcinogen or mutagen, all primary amines should be handled with care due to potential long-term risks
Aquatic Toxicity: Moderate to high toxicity to aquatic organisms
Persistence and Degradability: Not readily biodegradable, risk of persistence if released to the environment
Bioaccumulation Potential: Low, but can build up locally in water systems
Mobility in Soil: Moves easily, potential groundwater contaminant
Other Concerns: Release into waterways can cause acute harm to fish and invertebrates, disrupts local ecosystems
Handling of Waste: Collect liquid waste into sealed, clearly labeled drums or containers. Do not pour down drains or into soil.
Approved Disposal Methods: Incineration in a licensed chemical waste facility
Container Precautions: Empty drums or bottles should be triple-rinsed, punctured, and sent for specialized disposal
Legal Frameworks: Consult local, state, or national hazardous waste regulations for legal compliance
UN Number: UN 2733
Class: Flammable liquid (Class 3)
Packing Group: II (medium danger)
Label Requirements: Flammable liquid label must be clearly visible during transport
Transport Hazards: Avoid shock, flames, heat, or rough handling. Emergency response guide available from regulatory sources.
Bulk Transport: Tankers designed for flammable, toxic liquids with vapor containment and grounding features
Global Inventories: Listed in most chemical inventories such as TSCA, EINECS, and others
Regulated Uses: Restrictions exist in various sectors due to flammability, toxicity, and environmental risks
Worker Protection: Safety programs and hazard training required by OSHA, WHMIS, or equivalent agencies in many jurisdictions
Community Right-to-Know: Facilities using large quantities report storage and releases under environmental protection laws to keep communities informed and protected
