Description

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 micro extraction coupled to GC/MS in the selected ion monitoring mode. It 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
