Used in pharmaceutical research as a chiral intermediate for the synthesis of neuroactive compounds. Shows potential in the development of selective receptor modulators targeting central nervous system disorders. Its stereochemistry supports high enantioselectivity in drug candidates, particularly for treating neuropathic pain and psychiatric conditions. Also employed in asymmetric synthesis due to the rigid tetrahydroisoquinoline scaffold and well-defined stereocenters. The salt form enhances stability and crystallinity, facilitating purification and formulation in preclinical studies.
