Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) disorders. Its stereochemistry makes it valuable in creating selective drug candidates, including those targeting serotonin and dopamine receptors. Commonly employed in the production of antidepressants, antipsychotics, and kinase inhibitors. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid piperidine scaffold and functional group versatility.
