Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of drugs targeting the central nervous system. Its structure supports the development of compounds with high enantioselectivity, making it valuable in creating active ingredients for psychiatric and neurological treatments. Commonly employed in the preparation of dipeptidyl peptidase-4 (DPP-4) inhibitors for type 2 diabetes and other bioactive molecules requiring a piperidine scaffold. Its hydrochloride salt form enhances stability and solubility, facilitating use in various reaction conditions and purification processes during drug manufacturing.
