Used primarily as an intermediate in the synthesis of sulfonamide-based pharmaceuticals, particularly diuretic drugs such as furosemide and bumetanide. Its structure provides key functional groups that enable coupling reactions in drug manufacturing. It plays a critical role in introducing the sulfamoyl moiety into active pharmaceutical ingredients, enhancing their efficacy in treating hypertension, edema, and congestive heart failure. The compound is also utilized in research settings for developing new sulfonamide derivatives with potential biological activity.
