This chemical is primarily used as a reagent in organic synthesis, particularly in the preparation of sulfonamides. It reacts with amines to form sulfonamide derivatives, which are valuable in pharmaceutical research and development. The tert-butyl group enhances the stability of the compound, making it suitable for reactions requiring controlled conditions. Additionally, it is employed in the modification of polymers and resins, where sulfonyl chloride groups can introduce specific functional properties. Its application extends to the production of dyes and pigments, where it acts as an intermediate to create complex molecular structures.
