It is a colourless viscous oil that dissolves in organic solvents, but reacts with compounds containing reactive N-H and O-H bonds. It is mainly used to prepare sulfonamides and sulfonate esters by reactions with amines and alcohols, respectively. The closely related compound toluenesulfonyl chloride is often preferred analogue because it is a solid at room temperature and easier to handle. The compound is prepared by the chlorination of benzenesulfonic acid or its salts with phosphorus oxychloride[1] or, less commonly, by a reaction between benzene and chlorosulfuric acid. The Hinsberg test for amines involves their reaction with benzenesulfonyl chloride.[2] References1. ^Roger Adams, C. S. Marvel, H. T. Clarke, G. S. Babcock, and T. F.
