Product Name: Triethylamine hydrochloride
CAS Number: 554-68-7
Molecular Formula: C6H15N.HCl or C6H16ClN
Molecular Weight: 137.65
Appearance: White crystalline powder or colorless crystals, hygroscopic in air.
Solubility: Highly soluble in water (solubility ~ 245 g/L at 20°C), freely soluble in polar solvents such as ethanol and methanol, insoluble in nonpolar solvents like ether and benzene.
Melting Point: 254-256°C (decomposes upon heating).
pH: Aqueous solution is weakly acidic due to hydrolysis of the chloride ion.

Main Applications
Organic Synthesis:
Catalyst/Reagent:
Used as an acid-binding agent in condensation, acylation, and alkylation reactions to neutralize byproduct HCl.
Example: In peptide synthesis, it removes HCl generated during coupling reactions to maintain reaction pH.
Intermediate: Converted to triethylamine for use in pharmaceutical and agrochemical synthesis (e.g., in the production of antibiotics and herbicides).
Pharmaceuticals and Biotechnology:
pH Adjustment: In biochemical experiments, used to adjust buffer systems (e.g., in chromatography mobile phases).
Drug Formulation: As a salt form to improve the water solubility of basic drugs (though triethylamine itself has limited pharmaceutical use due to toxicity).
Electronics and Coatings:
Solvent Additive: In the production of coatings and electronic materials, regulates viscosity and improves film-forming properties.
Laboratory Reagent:
Commonly used in organic chemistry labs as a stable, easy-to-handle source of triethylamine (avoiding the volatility and odor of free-base triethylamine).

Safety and Handling
Hazards:
Health Risks:
Irritating to eyes, skin, and respiratory tract;
Ingestion may cause gastrointestinal irritation;
Triethylamine vapor (released upon decomposition) is toxic and has a strong odor.
Environmental Impact: May be harmful to aquatic life if released in large quantities; avoid direct discharge into water systems.
Protective Measures:
Wear gloves, safety goggles, and a lab coat; work in a fume hood to prevent inhalation of dust or decomposed vapors.
In case of skin/eye contact, rinse immediately with plenty of water; if inhaled, move to fresh air and seek medical attention.
Storage:
Store in a tightly sealed container in a cool, dry place, away from moisture and strong bases.
Keep separate from oxidizing agents and alkaline substances to avoid reactions.
