This compound is widely used in peptide synthesis and protein conjugation. It serves as a linker molecule, enabling the attachment of amino acids or peptides to other molecules, such as proteins or solid supports. The tert-butoxycarbonyl (Boc) group provides protection for the amino group during chemical reactions, ensuring selective modification. The N-succinimidyl ester moiety is highly reactive with primary amines, facilitating efficient coupling reactions. This makes it valuable in bioconjugation techniques for creating labeled proteins, antibodies, or other biomolecules for research, diagnostics, and therapeutic applications. Its stability and reactivity also make it suitable for use in drug delivery systems and the development of bioconjugates in targeted therapies.
