Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Its spirocyclic structure and nitrogen-containing ring make it valuable for designing drug candidates with improved metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in projects targeting neurological disorders. Also utilized in the preparation of novel heterocyclic systems for screening in antipsychotic and antidepressant drug discovery programs.
