Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals. It serves as a building block for peptidomimetics and enzyme inhibitors due to its structural similarity to amino acids. Commonly employed in solid-phase peptide synthesis where the Boc protecting group ensures selective reactivity. Its fluorinated aromatic side chain enhances binding affinity in drug candidates, making it valuable in medicinal chemistry for optimizing pharmacokinetic properties.
