Descripción general

Ethyl p-toluenesulfonate was used in a study to develop a fast and accurate method for determination of residues of some common alkylating agents employed in drug synthesis by in situ derivatization–headspace–gas chromatography–mass spectrometry. Ethyl p-toluenesulfonate was used to develop an extraction method for methyl and ethyl esters of various sulfonic acids in active pharmaceutical ingredients using solid-phase microextraction coupled to GC/MS in the selected ion monitoring mode.
