I. [Product Description]
Br-PEG-PEI (Bromide-Polyethylene Glycol-Polyethyleneimine) is a multifunctional organic intermediate that combines the high charge density of polyethyleneimine (PEI) with the biocompatibility of polyethylene glycol (PEG). It is suitable for gene vector construction, polymer material modification, and catalyst loading systems. Its unique brominated end groups can be further functionalized, which is of great value in controlled polymerization reactions and the synthesis of nanocomposites.
