Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure provides structural rigidity, which enhances selectivity and metabolic stability in drug candidates. Commonly employed in the preparation of bioactive molecules with potential antipsychotic, antidepressant, or cognitive-enhancing properties. Also utilized in medicinal chemistry research for scaffold diversification in high-throughput screening libraries.
