This chemical is primarily used in bioconjugation and click chemistry applications. Its structure, featuring azido and Boc-protected amine groups, makes it suitable for linking biomolecules or polymers in a controlled manner. The azide group enables efficient reactions with alkynes via copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the Boc-protected amines allow for selective deprotection and further functionalization. It is commonly employed in drug delivery systems, where it helps create stable, biocompatible linkages. Additionally, it is utilized in the synthesis of peptide-based therapeutics and materials, enabling precise modifications and enhancements of molecular properties. Its PEG (polyethylene glycol) chains improve solubility and reduce immunogenicity, making it valuable in biomedical research and therapeutic development.
