Used primarily in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds. It serves as a building block for developing receptor agonists and antagonists, particularly in neuroscience-related drug discovery. Its structure supports the design of molecules targeting central nervous system disorders, including cognitive and neurodegenerative conditions. Also employed in the development of chiral catalysts for asymmetric synthesis due to its amine functionality and rigid backbone. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction environments.
