Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. It serves as a building block in the production of certain antipsychotic and antidepressant drugs due to its structural compatibility with bioactive molecules. Also employed in the preparation of agrochemicals and specialty polymers where sulfur- and nitrogen-containing heterocycles enhance material properties. Its hydrochloride form improves stability and solubility in aqueous reaction media, facilitating easier handling in industrial processes.
