Used primarily in organic synthesis, it acts as a nucleophile in various reactions, particularly in the formation of thioethers and sulfides. It is also employed in the preparation of pharmaceuticals and agrochemicals, where it facilitates the introduction of sulfur-containing functional groups. Additionally, it serves as a key reagent in the synthesis of complex organic molecules, aiding in the construction of carbon-sulfur bonds. Its applications extend to material science, where it is used in the modification of surfaces and the development of sulfur-based polymers.
