This compound is primarily utilized in bioconjugation and click chemistry applications due to its azide functional group. It serves as a linker molecule, enabling the attachment of biomolecules, polymers, or other functional groups through efficient and selective reactions, such as the copper-catalyzed azide-alkyne cycloaddition (CuAAC). Its trioxa (ethylene glycol) chain provides water solubility and flexibility, making it suitable for modifying peptides, proteins, or nanoparticles in biological and materials research. Additionally, it is used in the development of drug delivery systems, surface functionalization, and the synthesis of complex macromolecules for biomedical applications.
