Triethylamine

Triethylamine is the chemical compound with the formula N(CH 2 CH 3) 3, commonly abbreviated Et 3 N. It is also abbreviated TEA, yet this abbreviation must be used carefully to avoid confusion with triethanolamine or tetraethylammonium, for which TEA is also a common abbreviation. It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia Triethylamine (TEA, Et3N) is an aliphatic amine. Its addition to matrix-assisted laser desorption/ionization (MALDI) matrices affords transparent liquid matrices with enhanced ability for spatial resolution during MALDI mass spectrometric (MS) imaging.

Medical definition of triethylamine: a water-soluble flammable liquid tertiary amine (C2H5)3N that is used chiefly in synthesis (as of quaternary ammonium compounds) Triethylamine is commonly employed in organic synthesis as a base, most often in the preparation of esters and amides from acyl chlorides. Such reactions lead to the production of hydrogen chloride which combines with triethylamine to form the salt triethylamine hydrochloride, commonly called triethylammonium chloride. This reaction removes the hydrogen chloride from the reaction mixture.
