Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. It serves as a structural building block for analgesics and psychotropic drugs due to its piperidine core and aryl substitution, which can influence receptor binding affinity. Commonly employed in the preparation of opioid receptor modulators and antidepressants. Also utilized in research settings for structure-activity relationship (SAR) studies of piperidine-based compounds. Its chlorophenyl group enhances lipophilicity, aiding in blood-brain barrier penetration, making it valuable in neuropharmacology.
