Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antipsychotic drugs. It serves as a building block for active pharmaceutical ingredients due to its structural similarity to proline and its ability to enhance metabolic stability in drug molecules. Commonly employed in the preparation of kinase inhibitors and receptor antagonists. Also utilized in the research and development of new medicinal compounds where a constrained piperidine scaffold improves binding affinity and selectivity.
