Used as an intermediate in organic synthesis, particularly in the preparation of sulfoxide and sulfonamide derivatives. It serves in the development of pharmaceuticals and agrochemicals due to its ability to act as a chiral auxiliary or building block in asymmetric synthesis. Also employed in the modification of peptides and proteins where sulfinamide groups can enhance stability or influence biological activity. Its reactivity allows for selective transformations in complex molecule assembly, making it valuable in medicinal chemistry research.
