I. [Product Description] 
    Mal-PEG-HZ (Maleimide-Polyethylene Glycol-Hydrazide) is a multifunctional organic intermediate that combines the high reactivity of maleimide groups with the excellent biocompatibility of PEG segments. It can be used as an efficient cross-linking agent or modifier in the fields of bioconjugation and material functionalization. Its hydrazide structure provides specific conjugation sites, suitable for the precise construction of biomolecular composite systems, and demonstrates excellent stability and controllability in reaction systems involving catalysts.
