This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, particularly in solid-phase peptide synthesis (SPPS). The fluorenylmethoxycarbonyl (Fmoc) group protects the amino group, while the benzyloxycarbonyl (Cbz) group protects the side chain amino group, ensuring selective reactions during peptide chain assembly. Its application is critical in producing peptides for pharmaceutical research, drug development, and biochemical studies, where precise control over peptide structure is essential.
