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 protects the alpha-amino group, while the benzyloxycarbonyl (Cbz) group protects the side chain amino group of lysine, ensuring selective reactions during peptide chain assembly. This compound is valuable in the production of peptides for research, pharmaceuticals, and biotechnology applications, where precise control over amino acid incorporation is critical. Its use allows for the synthesis of complex peptides with high purity and efficiency.
