N-(Azido-PEG4)-N-bis(PEG4-acid)(Cat No.:I015941)is a multifunctional PEG derivative featuring an azide group on a PEG₄ spacer and two terminal carboxylic acids connected through PEG₄ chains. The azide moiety enables highly selective bioorthogonal conjugation via copper-catalyzed or strain-promoted click chemistry, while the carboxyl groups can be activated for coupling with amines or hydroxyls to form stable linkages. The PEG₄ spacers impart excellent solubility, flexibility, and biocompatibility while minimizing steric hindrance. This versatile reagent is widely applied in bioconjugation, dual-site crosslinking, nanoparticle functionalization, and drug delivery system development.
