Used as a key intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It serves as a precursor in the development of biologically active molecules, including potential antitumor and antimicrobial agents. Its thione functionality allows for metal coordination, making it useful in catalysis and in the design of ligands for transition metal complexes. Also employed in the synthesis of dyes and functional materials due to its aromatic and sulfur-containing structure.
