Product Description
Triethylamine (TEA) is a colorless to pale yellow transparent liquid with a strong ammonia-like odor. It is a tertiary amine compound formed by replacing three hydrogen atoms in an ammonia molecule with ethyl groups. It is primarily used as a chelating agent, catalyst, emulsifier, and solvent. Triethylamine is highly soluble and miscible with organic solvents such as alcohols, ethers, esters, and aromatics. It is widely used in the pharmaceutical, pesticide, coatings, resin, rubber, and fine chemical synthesis industries.
