This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid building block, where the Fmoc (fluorenylmethyloxycarbonyl) group protects the amino functionality during the synthesis process. The presence of fluorine atoms on the phenyl ring enhances the stability and can influence the peptide's biological activity and binding properties. It is especially useful in creating peptides with specific structural or functional characteristics, such as those used in drug development, biochemical research, and the study of protein interactions. Its unique fluorinated side chain can also be leveraged to introduce specific electronic or steric effects in peptide design.
