This compound is widely used in bioconjugation and click chemistry applications. It serves as a linker molecule, enabling the attachment of biomolecules or other functional groups to surfaces or nanoparticles. Its azide group participates in copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, making it valuable for labeling, imaging, and drug delivery systems. Additionally, the benzyl group provides stability and hydrophobicity, while the PEG2 spacer enhances solubility and flexibility, making it suitable for use in aqueous and biological environments. It is particularly useful in the development of targeted therapies, diagnostics, and research tools in biochemistry and material science.
