Phenylthiocarbamyl

WebNov 11, 1994 · An improved HPLC method, using phenyl isothiocyanate (PITC) as derivatization agent, was developed for the separation and determination of 23 amino acids and triethanolamine in must and wine, without any pretreatment of the samples. The stability of dry and dissolved phenylthiocarbamyl derivatives was studied. WebPhenylthiocarbamyl (PTC) amino acid derivative is a precolumn derivatization method that has been widely used for analysis of amino acid by RP-HPLC (1–8). This method is an excellent method for the derivatization of secondary amino acids, proline, and hydroxyproline (2–4,7). However, its disadvantages are that it requires a high-vacuum ...
