Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. It serves as an intermediate in the production of central nervous system (CNS) agents, including certain antidepressants and antipsychotics. Its piperidine structure makes it valuable in medicinal chemistry for enhancing metabolic stability and binding affinity in drug molecules. Also employed in asymmetric synthesis and catalysis due to its chiral amine functionality.
