Used as an intermediate in organic synthesis, particularly in the preparation of sulfite esters and related sulfur-containing compounds. It serves as a mild sulfonating agent in specialized chemical reactions where controlled sulfur transfer is required. Employed in research settings for modifying organic molecules, especially in the development of pharmaceuticals and agrochemicals. Its reactivity makes it useful in radical reactions and as a protecting group reagent in multi-step syntheses. Also finds use in the formulation of certain lubricant additives due to its sulfur content, contributing to improved anti-wear properties.
