Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules due to the presence of both a nitrile group and a hydroxypiperidine moiety, which can enhance binding affinity and selectivity in drug candidates. Commonly employed in the production of antidepressants, antipsychotics, and cognitive enhancers. Also utilized in research settings for designing novel compounds with improved metabolic stability and blood-brain barrier penetration.
