This compound is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a building block for introducing modified phenylalanine residues into peptide chains. The Fmoc (fluorenylmethyloxycarbonyl) group acts as a protective group for the amino function, ensuring selective reactions during peptide assembly. The presence of the amino group at the para position of the phenyl ring allows for further functionalization, making it valuable in the development of peptides with specific biological activities or for conjugation with other molecules. It is often employed in the production of peptide-based drugs, research peptides, and bioconjugates, where precise control over amino acid incorporation is essential. Additionally, its use extends to the study of peptide-protein interactions and the design of bioactive peptides with enhanced stability or targeting capabilities.
