Used primarily in the synthesis of pharmaceuticals, it serves as a key intermediate in the production of sulfonamide-based drugs, which are effective antibiotics for treating bacterial infections. Additionally, it finds application in the development of diuretics and antidiabetic medications due to its sulfonamide functional group. In research, it is utilized to study the structure-activity relationships of sulfonamide derivatives, aiding in the discovery of new therapeutic agents. Its role in organic synthesis also extends to creating dyes and other specialty chemicals.
