Used as a key reagent in organic synthesis, particularly in radical reactions where it serves as a source of sulfur-centered radicals. It enables sulfination of various organic substrates under mild conditions, making it valuable in pharmaceutical and agrochemical manufacturing. Its reactivity in ring-opening and functionalization of heterocycles supports the development of complex molecules. The compound is also employed in polymer chemistry to introduce sulfinate groups, aiding in the modification of material properties such as solubility and thermal stability.
