This compound is widely used in bioconjugation and chemical biology due to its unique structure, which includes azide and Boc-protected amine groups. The azide group allows for click chemistry reactions, particularly copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling the attachment of biomolecules or probes. The Boc-protected amine provides a handle for further functionalization after deprotection, making it valuable in peptide synthesis and drug delivery systems. Its PEG (polyethylene glycol) spacers enhance solubility and reduce immunogenicity, making it ideal for creating biocompatible conjugates. Applications include the development of targeted drug delivery systems, labeling of proteins or antibodies, and the creation of complex biomolecular architectures for research or therapeutic purposes.
