Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its spirocyclic structure provides structural rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly found in research related to antipsychotic and antidepressant compounds due to its piperidine and isobenzofuran moieties, which are known to interact with neurotransmitter receptors. Also employed in the preparation of novel bioactive molecules in medicinal chemistry research.
