This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It acts as a building block for creating peptides with specific sequences, offering protection for the amino group during the reaction process. The Fmoc group ensures selective deprotection, while the Boc group safeguards the side chain functionality. It is especially useful in synthesizing peptides with D-amino acids, which are often employed in drug development and biochemical research due to their enhanced stability and resistance to enzymatic degradation. Its application is critical in producing peptides for therapeutic, diagnostic, and research purposes.
