I. [Product Description]
Epoxides-PEG-PEI is a multifunctional organic intermediate. Through the efficient coupling of epoxide groups, polyethylene glycol (PEG) segments, and polyethylenimine (PEI), it forms an amphiphilic polymer with controllable reactivity. Its core value lies in serving as a high-performance catalyst or functional carrier, which is widely used in the fields of polymer material synthesis and surface modification, and also meets the stringent requirements of pharmaceutical intermediates for biocompatibility and stability.
