Used as a key chiral intermediate in the synthesis of antidiabetic drugs, particularly DPP-4 inhibitors like saxagliptin and vildagliptin. Its stereochemistry enables selective binding to enzyme targets, enhancing drug efficacy. The compound's fluorinated aromatic structure improves metabolic stability and bioavailability in final pharmaceutical formulations. Commonly employed in asymmetric synthesis routes to ensure high enantiomeric purity in active pharmaceutical ingredients.
