BSC 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 or, less commonly, by a reaction between benzene and chlorosulfuric acid.
Novasol has REACH registered BSC as an intermediate in the 1 – 100 MT tonnage band.
