Used as a chiral building block in the synthesis of pharmaceuticals and bioactive molecules, particularly where enhanced metabolic stability and lipophilicity are desired. The perfluorophenyl group imparts strong electron-withdrawing properties and improves binding selectivity in peptide-based drugs. It is employed in medicinal chemistry for developing protease inhibitors and receptor ligands, taking advantage of its stereochemical purity to influence biological activity. Also utilized in materials science for designing fluorinated peptides with unique folding and self-assembly behavior.
