Used in pharmaceutical research as a key intermediate in the synthesis of potent sigma receptor ligands. Shows promise in the development of central nervous system agents, particularly for neurological disorders such as schizophrenia and Alzheimer's disease. Its spirocyclic structure enhances binding selectivity, making it valuable in optimizing drug candidates targeting cognitive and psychiatric conditions. Also employed in structure-activity relationship (SAR) studies to improve metabolic stability and blood-brain barrier penetration in neuroactive compounds.
