Chemical Name: 3-Aminopropene
Common Synonym: Allylamine
Molecular Formula: C3H7N
Physical Appearance: Colorless to pale yellow liquid, sharp odor
CAS Number: 107-11-9
Hazard Statements: Flammable liquid, causes severe burns to skin and eyes, appears toxic if inhaled, harmful after swallowing
Potential Health Effects: Workers have reported headache, dizziness, throat irritation, and respiratory discomfort around significant vapor concentrations. Eye contact has resulted in lasting irritation or damage.
Pictogram Links: Flammable, corrosive, toxic
Routes of Exposure: Inhalation, skin absorption, eye contact, ingestion
Main Component: 3-Aminopropene (purity varies, in labs often above 95%)
Impurities: May include traces of water, polymerized byproducts, amine analogs
Inhalation: Move exposed person to fresh air without delay; those overcome by vapor need immediate medical attention, no hesitation, use artificial respiration if breathing stops
Skin Contact: Remove contaminated clothing, rinse affected skin area right away with running water for at least 15 minutes, avoid scrubbing; serious burns require urgent medical care
Eye Contact: Rinse cautiously with water for many minutes, lift eyelids as much as possible, eye specialists should assess damage
Ingestion: Rinse mouth, never induce vomiting, seek hospital care immediately — do not gamble with home remedies
Supportive Care: Rescuers need nitrile gloves, safety goggles, and should avoid unprotected contact
Suitable Extinguishers: Alcohol-resistant foam, dry chemical, carbon dioxide preferred
Special Hazards: Releases toxic fumes of nitrogen oxides and carbon oxides on combustion, risk of violent flare-up if exposed to flames or sparks
Protective Equipment: Full self-contained breathing apparatus and chemical-resistant suit are a must; always tackle fires from upwind
Advice for Responders: Evacuate risk area, avoid breathing vapors, prevent runoff from entering sewers
Personal Precautions: Don’t take shortcuts: protective gloves, splash goggles, and chemical-resistant clothing
Spill Cleanup: Ventilate space, contain spill with inert absorbent (such as vermiculite), scoop up and place in sealed container, decontaminate area with diluted bleach—always neutralize residues
Environmental Protection: Keep product and clean-up waste out of drains, prevent ground and surface water contamination, inform local authorities about major accidents without delay
Safe Handling: Use only inside chemical fume hoods, ground all containers and lines to prevent static discharge, keep away from unshielded flames or direct heat
Storage: Store in tightly sealed containers made for corrosive liquid, keep away from oxidizers and acids, niche away from direct sunlight, position shelves low to minimize spill risk
Storage Conditions: Maintain cool, well-ventilated place with clearly marked hazard labeling—don’t store with food, feed, or incompatible chemicals
Engineering Controls: Local exhaust ventilation, chemical fume hoods
Occupational Exposure Limit: Specific limits for 3-Aminopropene differ by jurisdiction; many workplaces base guidance on ACGIH and OSHA standards, generally advising limits near 2 ppm for eight hours
Personal Protection: Splash goggles, butyl or nitrile gloves, flame-resistant lab coats, chemical-resistant footwear
Respiratory Protection: Wear full-face respirators with multi-gas cartridges if vapor risk exists or for spill cleanup
Boiling Point: Around 58 °C
Melting Point: Nearly -88 °C
Vapor Pressure: High at room temperature, expect rapid vaporization when spilled
Solubility: Miscible with water and many organics
Odor Threshold: Noticeable at low concentrations, pungent and irritant
Density: Roughly 0.76 g/cm³
Appearance: Clear to faint yellow low-viscosity liquid
Chemical Stability: Breaks down under prolonged heat or exposure to sunlight; can polymerize if left standing exposed
Incompatibility: Avoid strong acids, oxidizers, copper alloys
Hazardous Reactions: Rapid runaway possible with improper mixing, uncontrolled heat, or catalyst contamination
Decomposition: Releases ammonia, nitrogen oxides, carbon monoxide and carbon dioxide fumes with heat
Inhalation Effects: Strong lung irritant at low levels, can trigger coughing, shortness of breath, headache
Skin Effects: Severe burning and blistering common after splash
Eye Damage: Corneal burns, possible lasting vision loss reported in cases without prompt care
Acute Toxicity: Studies show LD50 (oral, rat) values hover around 215 mg/kg, which places it among more hazardous laboratory amines
Chronic Exposure: Regular jobs with poor controls have seen liver, kidney, and respiratory impacts
Aquatic Toxicity: Spills kill fish and invertebrates even at modest concentrations
Mobility: Product moves quickly through soil and groundwater without strict containment
Bioaccumulation: Organisms show low risk of long-term buildup, but short-term damage is acute after accidental contamination
Environmental Persistence: Sunlight and microbes break down most 3-Aminopropene within days to weeks, but local dead zones linger if cleanup gets botched
Preferred Disposal: Entrust all waste to licensed chemical handlers, incineration at authorized sites is safest
Drains and Landfills: Never flush product or residue down public drains—blockage and environmental breach fines are steep, and risks linger for years
Container Cleaning: Empty containers carry hazard, triple rinse with neutralizing solution before handling as scrap, keep lids on all the way to final disposal
UN Number: 2334 (for Allylamine)
Shipping Classification: Flammable liquid, toxic, corrosive
Packing Group: II (medium danger)
Special Precautions: Mark packages with clear hazard labeling, keep upright, never ship with acids or oxidizers, inform couriers about nature of risk so problems don’t compound in transit
Regulatory Listings: Many governments list 3-Aminopropene as a hazardous substance; transportation, emissions, and workplace exposure are regulated under frameworks like OSHA in the US, REACH in the EU, and the United Nations’ model regulations
Employer Responsibilities: Train staff in spill response, provide proper personal protective equipment, and conduct regular audits of ventilation, storage, and waste controls
Community Protection: Any major incident demands timely reporting to local health and environmental authorities, coordinated emergency planning with first responders, and transparent risk communication to community members living near sites using or storing this chemical
