Used as a key intermediate in organic synthesis, particularly in the preparation of sulfonamide derivatives. Its cyclic sulfamide structure enables ring-opening reactions that are valuable in pharmaceutical manufacturing. It acts as a sulfonating agent, transferring the sulfonamide group to amines and other nucleophiles under mild conditions. This makes it useful in the development of bioactive molecules, including antidiabetic and antimicrobial agents. The compound’s stability and reactivity profile allow for selective transformations in multi-step synthetic routes, especially in heterocyclic chemistry.
