This chemical is primarily utilized as an intermediate in the synthesis of various pharmaceutical compounds. Its chlorosulfonyl group makes it a valuable precursor for creating sulfonamide derivatives, which are often used in the development of drugs with antibacterial, anti-inflammatory, or diuretic properties. Additionally, it plays a role in the production of specialty chemicals and dyes, where its reactive sites enable modifications to enhance specific properties. Its application is also seen in organic synthesis for constructing complex molecules in research and industrial settings.
