Used in pharmaceutical research as a key intermediate in the synthesis of neuroactive compounds, particularly those targeting central nervous system disorders. Its spirocyclic structure and functional groups make it valuable for developing modulators of neurotransmitter receptors, including serotonin and dopamine pathways. Commonly employed in the creation of experimental therapeutics for depression, anxiety, and cognitive disorders. Also utilized in structure-activity relationship (SAR) studies to optimize potency and selectivity of novel drug candidates.
