This compound is widely used in peptide synthesis as a protected amino acid derivative. Its tert-butoxycarbonyl (Boc) group provides protection for the amine functionality, while the benzyl group safeguards the hydroxyl group during the synthesis process. The succinimidyl ester moiety enhances reactivity, facilitating efficient coupling with other amino acids or peptides. It is particularly valuable in solid-phase peptide synthesis, where selective deprotection of the Boc group allows for stepwise elongation of the peptide chain. Additionally, its stability and ease of handling make it a preferred choice in the preparation of complex peptides for pharmaceutical research and development.
