2,4-DINITROBENZENESULFONYL CHLORIDE Chemical Properties,Uses,Production

Chemical Properties

yellow crystalline powder

Uses

2,4-Dinitrobenzenesulfonyl chloride was used to protect primary amines. It was used as starting reagent in the synthesis of tert-butyl 2-[(2,4-dinitrophenyl) sulfonyl]amino acetate.

General Description

2,4-Dinitrobenzenesulfonyl chloride causes the sulfonation of glycosylamines to yield N-glycosyl-2,4-dinitrobenzenesulfonamides.

Purification Methods

Crystallise the sulfonyl chloride from *benzene or *benzene/pet ether. [Beilstein 11 H 78, 11 IV 214.]
