Used in peptide synthesis as a protecting group for amino acids, specifically to shield the amine group during the formation of peptide bonds. It is particularly valuable in solid-phase peptide synthesis (SPPS) due to its stability under basic conditions and ease of removal under mild conditions. The compound is also employed in the preparation of fluorescent peptides, as the Abz (anthranilic acid) moiety can act as a fluorophore, enabling the study of peptide interactions and dynamics. Additionally, it finds applications in the development of peptide-based drugs and biomaterials, where precise control over peptide sequence and structure is critical.
