Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) for drugs targeting various diseases. It serves as a key intermediate in the preparation of peptide-based therapeutics, enhancing the stability and bioavailability of the final compounds. Additionally, it is employed in asymmetric synthesis to create optically pure substances, which are crucial for developing enantioselective drugs. Its application extends to the field of medicinal chemistry, where it aids in the design and optimization of drug candidates with improved efficacy and reduced side effects.
