Used primarily in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators. It plays a significant role in the development of central nervous system (CNS) agents, particularly those targeting depression, anxiety, and neurological disorders. Due to its chiral structure, the (R)-enantiomer is preferred in bioactive compounds for higher selectivity and potency in receptor binding. It is also employed in structure-activity relationship (SAR) studies to optimize drug candidates targeting 5-HT receptors.
