This compound is widely used in peptide synthesis as a protecting group for amino acids, particularly in solid-phase peptide synthesis (SPPS). The fluorenylmethoxycarbonyl (Fmoc) group protects the amino group, while the benzyl group protects the hydroxyl group of homoserine. This dual protection allows for selective deprotection during the synthesis process, enabling the stepwise construction of complex peptides. Its application is crucial in the production of peptides for pharmaceutical research, drug development, and biochemical studies, where precise control over peptide sequences is required. Additionally, it is employed in the synthesis of modified peptides and peptidomimetics, which are important in designing therapeutic agents and studying protein interactions.
