Used primarily as a sulfenylating agent in organic synthesis, enabling the introduction of methanesulfinyl groups into various substrates. It serves as an intermediate in the preparation of sulfones, sulfoxides, and other sulfur-containing compounds with applications in pharmaceuticals and agrochemicals. Its reactivity makes it valuable for constructing complex molecules, particularly in the development of bioactive compounds. Due to its sensitivity to moisture and reactivity, it is typically handled under anhydrous conditions and used in controlled environments for selective transformations.
