Description and Uses
Benzenesulfonyl chloride is a colorless oilyliquid with a pungent odor. Molecular weight= 176.6;Specific gravity= 1.3842 at 15℃; Boilingpoint = 251- 252℃ (decomposes); Freezing/Meltingpoint= 15℃; Vapor pressure= 1 mmHg at 20℃; Relativevapor density (air=1) = 6.12; Flash point =130℃;Autoignition point = 460℃. Hazard Identification (based onNFPA-704 M Rating System): Health 3, Flammability 1,Reactivity 1. Moderately soluble in water.
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.
