Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. It serves as a building block in the production of certain antipsychotic and antidepressant agents due to the presence of the thiophene ring, which can enhance metabolic stability and binding affinity. Also employed in the preparation of agrochemicals and functional materials where aromatic amines are required. Its hydrochloride salt form improves solubility and handling in aqueous reaction systems.
