Used as an intermediate in organic synthesis, particularly in the preparation of sulfone derivatives through oxidation or coupling reactions. It serves as a building block in pharmaceuticals and agrochemicals where pyridine-based sulfinate structures are required for biological activity. Its sulfinate group allows for easy transformation into sulfonyl halides or sulfonamides, which are key motifs in drug design. Also employed in material science for synthesizing functionalized heterocyclic compounds with potential applications in electronic or optical materials.
