Chemical Name: Triethylamine Hydrochloride
CAS Number: 554-68-7
Concentration: >98% for laboratory grade
Impurities: Minor amounts of triethylamine, chloride ions, byproducts from synthesis
Hazardous Components: Main component responsible for toxicity and irritancy
Inhalation: Move affected person to fresh air, allow to rest and breathe deeply, seek medical advice if symptoms persist
Skin Contact: Wash thoroughly with plenty of water and mild soap, remove contaminated clothing, seek medical attention for persistent irritation
Eye Contact: Flush eyes with large amounts of water for at least fifteen minutes, seek prompt medical evaluation if irritation continues
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical attention
Symptoms: Burning, redness, coughing, headache in severe exposure
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam, water spray in case of fire
Unsuitable Extinguishing Media: Avoid direct water jet that may spread powder or dilute containment area
Specific Hazards from Fire: May generate toxic and corrosive gases such as hydrogen chloride and nitrogen oxides
Protective Equipment for Firefighters: Self-contained breathing apparatus and chemical protective clothing recommended
Special Procedures: Remove persons from immediate hazard area, avoid inhaling fumes, act to prevent spillwater from entering watercourses
Personal Precautions: Wear gloves, safety goggles, and dust mask or respirator, avoid direct contact, ventilate area
Environmental Precautions: Do not allow substance to enter drains, soil, or water systems
Methods for Cleaning Up: Scoop up material with non-sparking tools, place in sealable containers for disposal, wash area with plenty of water, ventilate wet areas after cleaning
Emergency Procedures: Evacuate untrained persons from spill area, contact emergency response professionals for large spills
Handling: Use with adequate ventilation or fume extraction, wear appropriate personal protective equipment, avoid breathing dust, practice good hygiene, keep container tightly closed when not in use
Storage: Store in a cool, dry, well-ventilated, and lockable storage room, away from incompatible materials like oxidizers and acids, label containers clearly, protect against moisture and humidity, do not store together with food or animal feed
Special Considerations: Keep away from flames, hot surfaces and sources of ignition, ensure spill containment equipment is available, check containers for integrity regularly
Recommended Engineering Controls: Laboratory fume hood or local exhaust ventilation to minimize airborne particles, safety showers and eye wash stations within immediate reach
Exposure Limits: No specific OSHA or ACGIH limits set; treat as irritant dust
Personal Protective Equipment: Splash goggles, lab coat, nitrile or neoprene gloves, dust or particulate respirator in case sufficient ventilation cannot be guaranteed
Hygiene Measures: Wash hands, face, and exposed skin after handling, launder work clothes regularly, avoid eating, drinking, or smoking in work area
Environmental Controls: Prevent release to environment, maintain spill response procedures
Appearance: White to off-white crystalline powder or solid
Odor: Faint ammoniacal odor
Molecular Weight: 137.65 g/mol
Melting Point: Approximately 261-263°C
Boiling Point: Decomposes before boiling
Solubility: Soluble in water, alcohol, insoluble in most nonpolar solvents
pH (aqueous solution): Acidic, varies with concentration
Vapor Pressure: Negligible at room temperature
Flash Point: Not applicable (nonvolatile solid)
Density: Around 1.05–1.10 g/cm3
Other Properties: Non-flammable, can produce irritating hydrogen chloride when heated strongly
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Reacts with strong oxidizers, acids, bases, and certain metals
Hazardous Reactions: Contact with alkalis and oxidants may produce hazardous materials
Conditions to Avoid: Avoid moisture, high temperatures, close proximity to incompatible chemicals
Decomposition Products: Produces hydrogen chloride, nitrogen oxides, and organic vapors on thermal decomposition
Routes of Exposure: Inhalation, skin or eye contact, ingestion
Acute Toxicity: Classified as irritant; data on median lethal dose (LD50 oral, rat): estimated over 2000 mg/kg
Chronic Effects: Prolonged exposure may cause skin and respiratory sensitization, long-term data lacking in literature
Symptoms of Overexposure: Redness, discomfort, coughing, headache, dizziness, eye watering from dust exposure
Sensitizing Effects: Not classified as sensitizer, but caution needed due to irritation risk
Potential Carcinogenicity: No components listed as carcinogens by IARC, NTP, or OSHA
Ecotoxicity: Data limited, can pose toxicity to aquatic organisms in high local concentration
Persistence and Degradability: Readily soluble; expected to break down in presence of moisture, but persistence in low water environments possible
Bioaccumulation Potential: Low
Mobility in Soil: Mobile due to water solubility, may leach to groundwater if spilled
Other Adverse Effects: Avoid large releases to prevent disruption to aquatic and terrestrial ecosystems
Disposal Methods: Dispose of as chemical waste through licensed contractor, according to local, state, and federal environmental regulations
Package Waste: Collect in sealed, properly labeled containers, segregate from incompatible waste streams
Contaminated Packaging: Rinse containers with water, dispose of rinsate as hazardous waste, recycle clean containers if possible following protocol, never reuse unwashed containers
Sewage Disposal: Do not allow to enter sewer systems
Special Precautions: Handle residues and free-flowing product in accordance with spill response guidelines
