Used as an intermediate in organic synthesis, particularly in the preparation of sulfonamides and other sulfur-containing compounds. It serves as a building block in pharmaceuticals and agrochemicals due to its ability to participate in sulfinylation reactions. Also employed in the development of chiral auxiliaries and catalysts for asymmetric synthesis. Its reactivity allows for the formation of C–N and C–S bonds under mild conditions, making it valuable in medicinal chemistry research.
