I. [Product Description]
Mal-PEG-EPOX (Maleimide-Polyethylene Glycol-Epoxide) is a multifunctional organic intermediate, which combines the high-efficiency click chemical reaction activity of maleimide groups with the ring-opening polymerization characteristics of epoxides. Its PEG chain can adjust the molecular weight, significantly improving water solubility and biocompatibility. It is widely used in the fields of bioconjugation, polymer material synthesis, and catalyst carrier construction. It is one of the core raw materials for the development of pharmaceutical intermediates.
