Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly found in compounds with antipsychotic, antidepressant, or anti-anxiety activity. Also employed in research settings to explore new bioactive molecules due to its favorable pharmacokinetic properties and ability to cross the blood-brain barrier.
