Used as a sulfur-containing building block in organic synthesis, particularly in the preparation of functionalized thiophenes and other heterocyclic compounds. Its dual thioester groups enable selective reactions with nucleophiles, making it valuable in the development of pharmaceuticals and agrochemicals. Also employed in polymer chemistry to introduce sulfur linkages, enhancing material flexibility and thermal stability. Additionally, it serves as a ligand precursor in coordination chemistry for metal-sulfur complex formation.
