Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain central nervous system agents and vasodilators. It serves as a building block in organic synthesis due to its amine functionality and rigid cyclic structure, enabling the development of bioactive molecules. Also employed in research settings for the preparation of selective serotonin reuptake inhibitors (SSRIs) and other neurologically active compounds. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction conditions.
