Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain central nervous system agents and antidepressant drugs. It serves as a building block for active pharmaceutical ingredients due to its amine and nitrile functional groups, which allow further chemical modifications. Commonly employed in research and development settings for creating novel compounds with potential biological activity. Its hydrochloride salt form improves stability and solubility, making it suitable for use in controlled reactions during drug manufacturing.
