2-Nitrobenzenesulfonyl chloride Chemical Properties,Uses,Production

Chemical Properties

Off-white tot yellow crystalline powder

Uses

2-Nitrobenzenesulfonyl chloride acts as a reagent to form 2-nitrobenzenesulfonyl derivatives of alcohols and amines. It is also involved in the selective cleavage with thiophenol without displacement of the nitro group. Further, it is used in the preparation of renin inhibitors. In addition to this, it finds application as an anticonvulsant.

Production Methods

2-Nitrobenzenesulfonyl chloride is isolated as an intermediate in the production of 2-nitrobenzenesulfonic acid. When 2,2' - dinitrodiphenyl disulfide is chlorinated in an organic solvent the product is 2-nitrophenylsulfenyl chloride.
