Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in developing central nervous system agents. Its spirocyclic structure provides structural rigidity, making it valuable in medicinal chemistry for enhancing selectivity and metabolic stability. Commonly employed in the development of kinase inhibitors and receptor modulators. Also utilized in the design of novel antidepressants and antipsychotics due to its favorable pharmacokinetic properties and ability to cross the blood-brain barrier.
