Used as an intermediate in organic synthesis, particularly in the preparation of sulfone and sulfoxide derivatives. It serves as a sulfination agent in pharmaceutical manufacturing, where it introduces sulfinate groups into target molecules. Commonly applied in the development of active pharmaceutical ingredients (APIs) requiring chiral sulfinyl functionalities. Also utilized in research settings for asymmetric synthesis due to its ability to form stereoselective bonds. Its reactivity makes it valuable in the production of agrochemicals and specialty chemicals.
