Used as a specialized reagent in organic synthesis, particularly in the preparation of sulfonamide derivatives. It serves as a sulfonylating agent, enabling the introduction of sulfonyl functional groups into target molecules, which is valuable in the development of pharmaceuticals and agrochemicals. Its cyclic structure and reactivity make it useful in constructing heterocyclic compounds with potential biological activity. Due to its stability and selectivity under controlled conditions, it is employed in research settings for the synthesis of novel sulfur-containing compounds.
