NH-bis(PEG3-azide)（Cat No.:I015913）is a bifunctional PEG-based crosslinker featuring a central amine core substituted with two PEG₃ chains, each terminating in an azide group. The azide functionalities enable efficient bioorthogonal click chemistry, including copper-catalyzed and strain-promoted cycloadditions, for site-specific and stable conjugation. The PEG₃ linkers provide hydrophilicity, molecular flexibility, and reduced steric hindrance, improving solubility and biocompatibility. This versatile reagent is widely applied in bioconjugation, crosslinking, surface functionalization, nanoparticle engineering, and drug delivery system design, where dual azide groups allow simultaneous or multivalent modification of biomolecules or materials.
