Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds. It serves as a chiral building block for developing selective receptor ligands, particularly in central nervous system drug discovery. Its structure supports high affinity binding to certain neurotransmitter receptors, making it valuable in the development of potential treatments for neurological and psychiatric disorders. The hydrochloride salt form enhances stability and solubility, which is beneficial for formulation in preclinical studies.
