Used as a reagent in organic synthesis, particularly in the preparation of sulfenylated compounds. It serves as a source of the S-phenylsulfenyl group in the modification of thiols and other nucleophiles. Employed in the development of pharmaceuticals and agrochemicals where controlled sulfur incorporation is required. Also utilized in studies of sulfur transfer reactions and in the synthesis of chiral sulfoxides when used with asymmetric catalysts. Its stability and selective reactivity make it valuable in multi-step synthetic routes.
