Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of protease inhibitors and antiviral drugs. Its fluorinated aromatic structure and stereochemical purity make it valuable for enhancing metabolic stability and target selectivity in drug candidates. Commonly employed in the development of treatments for hepatitis C and other viral infections due to its role in mimicking natural amino acid substrates. Also utilized in medicinal chemistry research for structure-activity relationship studies involving enzyme inhibitors.
