Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure with a fluorine substituent enhances metabolic stability and blood-brain barrier penetration, making it valuable in designing bioactive molecules. Commonly employed in medicinal chemistry for optimizing potency and selectivity in drug candidates targeting neurological disorders. Also utilized in the preparation of kinase inhibitors and receptor modulators due to its favorable conformational rigidity and hydrogen bonding capability.
