I. [Product Description]
Aminooxy-PEG-PEI is a multifunctional polymer coupling compound composed of an aminomethyl active group, a polyethylene glycol (PEG) segment, and polyethyleneimine (PEI). It combines the reactivity of organic intermediates with the biocompatibility of PEG modification. Its aminooxy group can specifically bind to carbonyl compounds and is widely used in biomolecule cross-linking, nanocarrier construction, and catalytic system optimization. It is a key reagent for the development of pharmaceutical intermediates and the synthesis of functional materials.
