Triethylamine Hydrochloride is a hydrochloride salt of triethyllamine (T775740). Triethylamine is used as a competing base for the separation of acidic basic and neutral drugs by reverse-phased high-performance liquid chromatography (HPLC). Triethylamine induces visual disturbances (such as foggy vision) in humans, and is also used in industry as a quenching agent in the ozonolysis of alkenes (e.g. (E)-2-Pentene [P227315]). Triethylamine is used in the purification of drugs which are pharmacologically or chemically similar through separation in reverse-phase HPLC (2).Drinking water contaminant candidate list 3 (CCL 3) compound as per United States Environmental Protection Agency (EPA).
