I. [Product Description] 
PEG-Mal (Polyethylene Glycol-Maleimide) is a highly efficient multifunctional organic intermediate that combines excellent biocompatibility with controllable reaction activity. It is widely used in the synthesis of pharmaceutical intermediates and the catalytic modification of polymer materials. Its maleimide group can specifically undergo a click chemical reaction with thiol groups. Combining the hydrophilicity and adjustable molecular weight characteristics of the PEG segment, it is a core reagent for constructing functionalized materials.
