Used as a key intermediate in the synthesis of sulfa-based pharmaceuticals, particularly in the production of carbonic anhydrase inhibitors like acetazolamide and methazolamide. These drugs are primarily employed to treat glaucoma, epilepsy, and certain types of edema. The compound’s structure allows for selective binding to enzyme active sites, enhancing therapeutic efficacy. It is also utilized in the development of diuretic agents due to its ability to influence electrolyte reabsorption in the kidneys. Its role in medicinal chemistry makes it valuable in research and industrial drug manufacturing.
