This chemical is primarily used in bioconjugation and click chemistry applications. Its structure, featuring PEG (polyethylene glycol) spacers and azide groups, makes it highly suitable for linking biomolecules or polymers in a controlled and efficient manner. The Boc (tert-butoxycarbonyl) group provides temporary protection for amines during synthesis, allowing selective deprotection when needed. The azide groups enable copper-catalyzed azide-alkyne cycloaddition (CuAAC), a widely used click reaction, to form stable triazole linkages. This compound is particularly useful in the development of drug delivery systems, where it can be employed to create PEGylated conjugates that enhance solubility, stability, and bioavailability of therapeutic agents. Additionally, it finds applications in the fabrication of hydrogels, surface modification of materials, and the synthesis of complex macromolecular architectures for biomedical research.
