Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of protease inhibitors and other bioactive molecules. Its fluorinated aromatic group enhances binding affinity and metabolic stability in drug candidates. Commonly employed in asymmetric synthesis to introduce stereoselectivity. Also utilized in the preparation of peptidomimetics due to the presence of the protected amino acid functionality. Suitable for solid-phase and solution-phase peptide synthesis when deprotected.
