Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and trifluoromethyl group enhance metabolic stability and binding selectivity, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly employed in the preparation of kinase inhibitors and neuromodulatory drugs due to its favorable pharmacokinetic properties and ability to cross the blood-brain barrier. Also utilized in research settings to explore new bioactive molecules with improved potency and reduced off-target effects.
