2,4-DINITROBENZENESULFONYL CHLORIDE Usage And Synthesis
Chemical Propertiesyellow crystalline powder
Uses2,4-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 Description2,4-Dinitrobenzenesulfonyl chloride causes the sulfonation of glycosylamines to yield N-glycosyl-2,4-dinitrobenzenesulfonamides.
Purification MethodsCrystallise the sulfonyl chloride from *benzene or *benzene/pet ether. [Beilstein 11 H 78, 11 IV 214.]
