Used in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) drugs. It serves as a key intermediate in creating molecules that target neurological disorders such as anxiety, depression, and schizophrenia. Its spirocyclic structure is valuable for designing drugs with enhanced binding affinity and selectivity for specific receptors in the brain. Additionally, it is utilized in research to explore novel therapeutic agents and to study the pharmacological properties of spirocyclic compounds.
