Applications
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.

Solubility
Insoluble in water.

Notes
Moisture sensitive. Store away from oxidizing agent.
