Used as a chiral building block in the synthesis of fluorinated pharmaceuticals and bioactive compounds. Its perfluorinated aromatic group enhances metabolic stability and lipophilicity, making it valuable in drug design for improving membrane permeability and resistance to oxidative degradation. Commonly employed in peptide mimetics and enzyme inhibitors where fluorine substitution modulates biological activity. Also applied in materials science for creating specialty polymers with unique surface properties due to the strong electron-withdrawing nature of the perfluorophenyl group.
