This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides with specific sequences, particularly in solid-phase peptide synthesis (SPPS). The fluorenylmethoxycarbonyl (Fmoc) group acts as a protecting group for the amino functionality, ensuring selective reactions during peptide chain elongation. The 3'-chloro-[1,1'-biphenyl]-4-yl moiety introduces a hydrophobic and aromatic character, which can be useful in designing peptides with specific structural or binding properties. This compound is especially valuable in research and development of pharmaceutical peptides, where precise control over amino acid incorporation is critical. Additionally, its unique structure may contribute to the study of peptide-protein interactions or the development of bioactive peptides.
