This compound is primarily used in peptide synthesis as a protected amino acid derivative. The fluorenylmethoxycarbonyl (Fmoc) group serves as a protecting group for the amino functionality, allowing selective deprotection during solid-phase peptide synthesis. Its incorporation enables the construction of complex peptides with specific sequences, particularly those requiring fluorinated aromatic side chains. The fluorine atom on the phenyl ring can influence the peptide's biological activity, stability, and binding properties, making it valuable in the development of pharmaceuticals and bioactive peptides. Additionally, it is utilized in research to study the effects of fluorination on peptide structure and function.
