Used in pharmaceutical research as a key intermediate in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its spirocyclic structure provides conformational rigidity, making it valuable for designing bioactive molecules with improved receptor selectivity. Commonly employed in the development of antidepressant and anxiolytic drug candidates due to its ability to modulate neurotransmitter activity. Also utilized in structure-activity relationship (SAR) studies to optimize potency and metabolic stability in novel piperidine-based therapeutics.
