Component: Triethylamine Hydrochloride
Chemical Formula: C6H15N·HCl
Concentration: Pure or near pure compound for laboratories
Impurities: Minimal, only trace impurities meet analytical standards
Other Components: No significant stabilizers, processing aids, or additives included
Inhalation: Remove exposed person to fresh air immediately; if breathing difficulty persists, seek medical attention; respiratory discomfort can present as coughing, throat tightness, or difficulty in breathing
Skin Contact: Wash exposed area thoroughly with soap and water for at least 15 minutes; remove contaminated clothing and launder before reuse; if irritation or redness appears, consult a physician
Eye Contact: Flush eyes with copious amounts of water for a minimum of 15 minutes, lifting eyelids to ensure thorough rinsing; avoid rubbing eyes, seek medical attention if burning or discomfort continues
Ingestion: Rinse mouth with clean water; do not induce vomiting unless instructed by a medical provider; if feeling unwell, seek immediate medical attention
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide for surrounding fire context
Specific Hazards: In fire conditions, toxic and corrosive gases such as hydrogen chloride, nitrogen oxides, and carbon oxides may be released
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective clothing; avoid inhalation of combustion products; evacuate area if large quantities involved
Firefighting Instructions: Use water spray to cool containers exposed to fire; prevent fire-fighting runoff from entering drains or waterways
Personal Precautions: Wear dust mask, gloves, and chemical safety goggles; avoid contact with skin, eyes, and clothing; prevent dust formation
Environmental Precautions: Prevent spillage from entering soil, sewers, and waterways; alert authorities if significant leaks occur
Clean-Up Procedures: Sweep up material without creating dust; collect in suitable containers for recovery or disposal; ventilate spill areas and wash surfaces with water; dispose of in compliance with local, regional, and national requirements
Handling: Only handle in areas with adequate ventilation; avoid dust generation and spreading; always wear recommended personal protective equipment; wash thoroughly after handling, especially before eating or drinking
Storage: Store in tightly closed containers in a cool, dry, and well-ventilated place; keep away from incompatible substances, such as oxidizing agents and strong acids or bases; clearly label containers; secure area against unauthorized access
Engineering Controls: Use fume extraction systems, local exhaust, or work in a chemical safety hood to limit exposure to airborne particles
Eye Protection: Chemical splash-proof goggles or safety glasses with side shields
Skin Protection: Wear suitable gloves (nitrile or neoprene recommended), lab coat, and closed-toe shoes
Respiratory Protection: Use a particulate respirator if dust is generated; follow regulatory fit-testing and selection standards
Hygiene Measures: Wash hands and exposed skin after handling; avoid eating, drinking, or smoking during work; do not take contaminated clothing out of the work area until properly cleaned
Appearance: White to off-white crystalline powder
Odor: Characteristic amine-like odor
Molecular Weight: 137.66 g/mol
Melting Point: 261-263°C
Boiling Point: Decomposes before boiling
Solubility: Readily soluble in water, forming clear solution
pH (1% Solution): Slightly acidic
Vapor Pressure: Not volatile or significant at room temperature
Flash Point: Not combustible as a solid
Density: Approximately 0.93–1.05 g/cm³ at 20°C
Chemical Stability: Stable under recommended storage and handling conditions
Incompatible Materials: Strong oxidizers, acids, alkalis; reacts with water liberating heat, but not violently
Hazardous Decomposition Products: Emits hazardous fumes such as hydrogen chloride and nitrogen oxides when heated or combusted
Conditions to Avoid: Avoid excess heat, sources of ignition, contact with reactive chemicals, moisture ingress in long-term storage
Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Can cause coughing, nausea, headache, or skin redness with direct contact; high doses may cause systemic effects
Chronic Effects: Extended or repeated contact irritates skin and may provoke dermatitis, respiratory discomfort, or sensitivity in susceptible people
Symptoms: Burning sensations, tearing, coughing, abdominal pain or distress, skin itching or rash
Carcinogenicity: Data does not indicate carcinogenic effects at occupational exposure limits
Mutagenicity and Reproductive Effects: No evidence from available literature suggesting mutagenic or reproductive harm at normal exposures
Ecotoxicity: May be toxic to aquatic organisms at high concentrations; potential for acute or chronic disturbance in fish, daphnia, and algae
Persistence and Degradability: Breaks down in soil and water, but excessive release may disrupt water bodies; low potential for bioaccumulation
Mobility in Soil: Highly soluble in water; can migrate through soil and affect groundwater if spilled
Other Adverse Effects: Decomposed material in aquatic environments may lower pH, threatening aquatic life; avoid large-scale releases into waterways
Waste Treatment Methods: Dispose as hazardous laboratory waste, incinerate under controlled conditions if permitted; use chemical-resistant containers
Contaminated Packaging: Rinse thoroughly before recycling or disposal, or dispose of packaging as hazardous waste if contaminated
Disposal Regulations: Observe all federal, state, and local laws on safe disposal of chemicals; coordinate with licensed waste contractors
Waste Code: Assign code in line with regional and local hazardous waste listings
