Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its spirocyclic structure and nitrile functional group make it valuable for constructing complex organic molecules with biological activity. Commonly employed in medicinal chemistry for modifying drug candidates to improve metabolic stability and binding affinity. Also utilized in the preparation of opioid receptor modulators due to the presence of the cyclopropylmethyl group, which is known to influence receptor selectivity and potency.
