I. [Product Description]
VA-PEG-PEI (Valeric acid-Polyethylene glycol-Polyethyleneimine) is a high-molecular organic intermediate with an amphiphilic structure. Through the efficient coupling of the valeric acid group with the amine group of PEI and combined with the biocompatibility of the PEG segment, it can be used as a pharmaceutical intermediate to prepare functionalized complexes. Its tertiary amine structure and modifiable sites enable it to exhibit excellent proton buffering capacity and molecular self-assembly properties in the catalytic system.
