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 amino group, while the tert-butoxycarbonyl (Boc) group protects the secondary amine, ensuring selective reactivity during peptide chain assembly. Its application is crucial in producing peptides for research, pharmaceuticals, and biotechnology, enabling the development of therapeutic agents, vaccines, and biochemical tools.
