This chemical is primarily used as an intermediate in the synthesis of various pharmaceutical compounds. It plays a key role in the production of sulfonamide-based drugs, which are widely used for their antibacterial properties. Additionally, it is utilized in the development of organic compounds with potential therapeutic applications, such as enzyme inhibitors or receptor modulators. Its sulfonyl and carboxylic acid functional groups make it a versatile building block in medicinal chemistry for designing molecules with specific biological activities.
