Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active drugs. It serves in the preparation of selective receptor antagonists and agonists, especially targeting serotonin, dopamine, and sigma receptors. Commonly employed in the manufacture of analgesics, antipsychotics, and antidepressants. Its structural features make it valuable in medicinal chemistry for modifying pharmacokinetic properties such as bioavailability and blood-brain barrier penetration. Also utilized in research settings for generating novel piperidine-based compounds during drug discovery.
