General description

3-Bromobenzenesulfonyl chloride is an aryl sulfonyl chloride derivative. It participates in the synthesis of N-sulfonylanthranilic acid derivatives and potent P1′ benzenesulfonyl azacyclic urea human immunodeficiency virus (HIV) protease inhibitors.

Application

3-Bromobenzenesulfonyl chloride may be used in the preparation of:
  • 2-(3-bromophenyl)-5-n-butylfuran
  • 2-(3-bromophenyl)-3,6-dimethyl-4,5,6,7-tetrahydrobenzofuran
  • 3-bromo-4-(3-bromophenyl)thiophene
  • 2,5-bis(3-bromophenyl)-1-methylpyrrole
