Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients that require heterocyclic structures. Its reactivity allows for the introduction of the thiophene ring into larger molecules, enhancing stability and biological activity. Commonly employed in the production of dyes and functional materials where sulfur-containing aromatic systems improve electronic properties. Also utilized in research for developing new organic semiconductors and ligands for metal-catalyzed reactions.
