Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of antidiabetic drugs such as DPP-4 inhibitors. Its stereochemistry enables selective interactions in biological systems, enhancing drug efficacy and reducing side effects. Commonly employed in the preparation of active pharmaceutical ingredients requiring high enantiomeric purity. Also utilized in research settings for the construction of fluorinated heterocyclic compounds to study metabolic stability and bioavailability.
