Used in pharmaceutical research as a key intermediate in the synthesis of centrally acting agents, particularly in the development of dopamine and serotonin receptor modulators. Its structural features make it valuable for optimizing bioavailability and target selectivity in neuroactive compounds. Also explored in the design of novel treatments for neurological disorders such as depression, anxiety, and Parkinson’s disease. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its conformational rigidity and heterocyclic framework.
