Triethylamine is a mobile-phase modifier in RP-HPLC separation of acidic, basic, and neutral drugs. Improves resolution of amino acids and amino acid amides by HPLC by suppressing tailing. Triethylamine is employed in organic synthesis in the preparation of esters and amides from acyl chlorides. It is also useful in dehydrohalogenation reactions and Swern oxidations.
