Used in peptide synthesis as a protected amino acid derivative, it facilitates the incorporation of phenylalanine with a cyano group at the 3-position (meta) of the phenyl ring into peptide chains. The Boc (tert-butoxycarbonyl) group serves as a protective moiety for the amino group, ensuring selective reactions during peptide bond formation. This compound is particularly valuable in the development of bioactive peptides and peptidomimetics, where the cyano group can enhance binding affinity or modulate biological activity. It is also employed in medicinal chemistry research to explore structure-activity relationships in peptide-based drug candidates.
