I. [Product Introduction]
HZ-PEG-PEI Hydrazide-Polyethylene Glycol-Polyethyleneimine is a multifunctional organic intermediate with both high-efficiency catalytic carrier and polymer modification properties. Its hydrazide group can be used for the directional coupling of active molecules, the PEI backbone provides high charge density, and the PEG segment enhances water solubility and biocompatibility. It is suitable for the synthesis of pharmaceutical intermediates and the construction of nanocatalytic systems.
