Used as an efficient sulfinate source in organic synthesis, particularly in radical reactions for the introduction of sulfonyl groups. It serves as a key reagent in sulfonylation processes under mild conditions, enabling the formation of sulfones through transition-metal-free or photoredox-catalyzed pathways. Its stability and solubility in common organic solvents make it suitable for use in pharmaceutical and agrochemical synthesis where controlled sulfinate delivery is required. Also employed in cross-coupling reactions to construct C–S bonds, contributing to the development of functional materials and bioactive molecules.
