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 safeguards the side-chain amino functionality. This dual protection allows for selective deprotection during peptide chain assembly, ensuring precise control over the synthesis process. It is especially valuable in producing peptides for pharmaceutical research, drug development, and biochemical studies, where high purity and specific sequences are critical.
