This chemical is primarily used in peptide synthesis as a protected amino acid derivative. The fluorenylmethoxycarbonyl (Fmoc) group serves as a protecting group for the amino function, allowing for selective deprotection during the synthesis process. It is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps in the stepwise assembly of peptide chains. The methoxyphenyl side chain can contribute to the peptide's overall structure and function, potentially influencing its biological activity or binding properties. This compound is essential in the production of complex peptides for research, pharmaceuticals, and biotechnology applications.
