IUPAC Name: N,N-Diethylpropane-1,3-diamine
CAS Number: 101-23-5
Appearance: Colorless to pale yellow liquid with a strong ammoniacal odor
USES: This compound finds its place mostly in specialty chemical synthesis, resin modification, or as a curing agent and corrosion inhibitor in industrial settings.
Hazard Class: Harmful if swallowed, causes severe skin burns and eye damage
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Pictograms: Corrosive symbol, exclamation mark for irritant properties
Main Symptoms: Burning sensation, coughing, wheezing, eye redness, blurred vision, blistering
Health Risks: Respiratory tract irritation, risk of chemical pneumonitis if inhaled as vapor, severe chemical burns on skin and mucosa, potential for long-term damage to vision
Environmental Impact: Harmful to aquatic life, especially fish and invertebrates
Chronic Effects: No definitive links to cancer, but chronic skin exposure can cause dermatitis or skin sensitization in some workers
Ingredient: N,N-Diethyl-1,3-propanediamine
Concentration: Typically above 99% pure in commercial contexts
Other Ingredients: Residual amines or water as trace impurities from synthesis
Inhalation: Move affected individual to fresh air; keep warm and at rest; get medical attention if symptoms continue
Skin Contact: Remove contaminated clothing, rinse skin with plenty of running water; seek medical care promptly if irritation or burns develop
Eye Contact: Rinse eyes immediately with plenty of water for at least 15 minutes, lifting eyelids; urgent ophthalmological care needed
Ingestion: Rinse mouth, do not induce vomiting, monitor breathing and consciousness, seek immediate medical attention
Notes to Doctors: Treat for chemical injury, monitor for airway compromise, and consider symptomatic therapy for burns and respiratory distress
Flammability: Not highly flammable, but heated vapors can ignite
Suitable Extinguishing Media: Carbon dioxide, dry powder, foam; water spray for cooling containers
Fire Hazards: Toxic and corrosive gases such as nitrogen oxides and carbon monoxide can result from combustion
Protective Equipment: Full protective gear, self-contained breathing apparatus due to risk of inhaling toxic fumes
Firefighting Tactics: Cool exposed containers with water spray to reduce risk of rupture; avoid breathing vapors and runoff can be hazardous for the environment
Personal Precautions: Wear chemical-resistant gloves, goggles, face protection, impervious clothing
Ventilation: Use with adequate ventilation or in a chemical fume hood
Containment: Prevent spillage from entering drains, watercourses, or soil
Cleanup: Neutralize with mild acid (like acetic acid solution), absorb with inert material (sand, earth), shovel up and dispose of following hazardous waste rules
Decontamination: Wash spill area thoroughly with plenty of water after cleanup
Handling: Avoid breathing vapors, prevent skin and eye contact, use with care in closed systems or ventilated areas
Storage: Keep container tightly closed, store in a cool, well-ventilated spot away from direct sunlight, oxidizers, acids, and moisture
Segregation: Store separately from incompatible substances such as acids and oxidizing agents
Container Integrity: Regularly check chemical drums or bottles for leaks or damage, keep away from heat sources
Engineering Controls: Install local exhaust ventilation, chemical fume hoods, emergency showers, and eye wash stations in work areas
Personal Protection: Chemical goggles, face shield for splash risk, neoprene or nitrile gloves, chemical-resistant clothing
Respiratory Protection: Where vapor or aerosol concentration may exceed limits, use appropriate NIOSH-approved respirator
Exposure Limits: No established OSHA PEL, but minimize airborne concentration and consult industrial hygiene guidance
Hygiene Measures: Wash hands before breaks and at end of work, avoid eating or drinking in work zones
State: Liquid
Color: Colorless to pale yellow
Odor: Ammoniacal, pungent
Boiling Point: 178-180°C
Melting Point: Not applicable, remains liquid at room temperature
Solubility: Miscible with water
Density: Around 0.85 g/cm³ at 20°C
pH: Alkaline in aqueous solution
Vapor Pressure: Relatively low, but still can produce irritating vapors
Flash Point: Estimated above 50°C (closed cup; check MSDS for detailed value if available)
Stability: Stable under most recommended storage conditions
Reactivity: Reacts with acids, strong oxidizers; heat, light, and moisture can accelerate degradation
Hazardous Polymerization: Not expected under normal conditions
Decomposition Products: Toxic fumes of nitrogen oxides, carbon monoxide and carbon dioxide in case of fire
Incompatible Materials: Strong acids, oxidizers, acyl chlorides, acid anhydrides; can react violently
Acute Toxicity: Oral and dermal exposure both cause burns; ingestion could lead to mouth, throat, stomach corrosive injuries
Inhalation: Exposure to vapors can result in respiratory irritation; high concentrations may lead to lung injury
Skin Contact: Burns with blistering, redness, and long-lasting scars are possible without swift decontamination
Eye Contact: Splash or vapor can damage the cornea and conjunctiva; prolonged exposure risks permanent visual impairment
Sensitization: Prolonged contact sometimes results in allergic reactions, usually dermatitis-like symptoms
Chronic Effects: Not classified as carcinogenic, mutagenic, or reproductive toxicant in standard regulatory lists
Aquatic Toxicity: Harmful to aquatic organisms, can cause acute toxicity in fish and invertebrates, may trigger algal blooms due to basicity
Persistence and Degradability: Not highly persistent, but can alter water pH and disrupt microbial communities
Bioaccumulation: Likelihood appears low based on water solubility and structure
Behavior in Sewage Plants: May interfere with biological treatment processes if released in significant amounts
Preventing Pollution: Contain spills, do not flush into drains
Waste Disposal: Treat as hazardous chemical waste; incinerate or use licensed hazardous waste contractors
Container Disposal: Triple rinse empty containers, consider recycling plastic or metal if regulations allow, otherwise treat as hazardous waste
Pollution Prevention: Do not allow residual liquid to enter natural waters, drain systems, or municipal waste streams
Legal Standards: Adhere to local, regional, and national hazardous waste regulations to minimize risk of illegal dumping
