I. [Product Description]
NPC-PEG-PEI (Nitrophenyl carbonate-Polyethylene glycol-Polyethyleneimine) is a multifunctional organic intermediate that combines the characteristics of a polymer carrier and reactive groups. It is widely used in polymer synthesis and catalytic reaction systems. The PEG segment in its structure provides excellent water solubility and biocompatibility. The nitrophenyl carbonate group can serve as a highly efficient activation site for specific coupling with functional groups such as amino groups, making it of great value in the preparation of pharmaceutical intermediates and catalyst immobilization.
