Application

Benzenesulfonyl chloride may be used to develop fast, accurate and reproducible method for thiamine assay in different food products1. It is useful reagent for preparing α-disulfones2.

General description

Benzenesulfonyl chloride is prepared by reaction of benzene and chlorosulfonic acid or from the sodium salt of benzenesulfonic acid and PCl5 or POCl33. It reacts with Grignard reagent from N-unsubstituted indoles to form oxindoles or substituted indoles4. Benzenesulfonyl chloride is the derivatization reagent for the determination of various amines in waste water and surface water at the sub-ppb level by gas chromatography-mass spectrometry5.
