Used as a key intermediate in organic synthesis, particularly in the preparation of sulfoxide-containing compounds which are important in pharmaceuticals and agrochemicals. It serves as a sulfination reagent in cross-coupling reactions, enabling the introduction of sulfinyl groups into aromatic systems. Its stability and solubility profile make it suitable for use in aqueous and mixed solvent systems, facilitating reactions under mild conditions. Also employed in the development of functional materials and in medicinal chemistry for constructing biologically active molecules.
