This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing complex peptides and proteins, particularly in solid-phase peptide synthesis (SPPS). The fluorenylmethoxycarbonyl (Fmoc) group protects the amine functionality, while the tert-butoxycarbonyl (Boc) group safeguards the side chain amine, ensuring selective deprotection and coupling during the synthesis process. Its application is critical in the production of peptides for pharmaceutical research, drug development, and biochemical studies, where precise control over peptide sequence and structure is essential.
