General description

Benzenesulfonyl chloride reacts with Grignard reagent from N-unsubstituted indoles to form oxindoles or substituted indoles[1]. It 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 spectrometry[2].

Application

Benzenesulfonyl chloride may be used in thiamine assay for determination of thiamine in different food products[3].
