Benzenesulfonyl chloride reacts with Grignard reagents to form oxindoles from N-unsubstituted indoles. It is widely used to check the assay of thiamine in different food products. It is involved in the synthesis of alpha-disulfones, sulfonamides and sulfoante esters as precursor. It is a derivatization reagent for the determination of various amines in waste water and surface water at the sub-ppb level by gas chromatography-mass spectrometry. It is common reagent used in Hinsberg test for detection and distinguishing the type of amines as primary, secondary and tertiary amines.

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.
