Used primarily in organic synthesis, this compound serves as a key intermediate in the production of sulfonamide derivatives. It is particularly valuable in the pharmaceutical industry for creating active pharmaceutical ingredients (APIs) with sulfonamide functional groups, which are essential in various drugs, including antibiotics and diuretics. Additionally, it finds application in the development of agrochemicals, where sulfonamide-based compounds are used as herbicides or fungicides. Its reactivity with amines and other nucleophiles makes it a versatile building block in the synthesis of complex molecules for research and industrial purposes.
