Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Shows potential in the design of receptor modulators due to its ability to cross the blood-brain barrier. Also employed in structure-activity relationship (SAR) studies for optimizing potency and selectivity in drug candidates targeting neurological disorders. Its hydrochloride salt form enhances solubility and stability, making it suitable for in vitro and in vivo testing.
