I. [Product Description]
PEG-bisCOOH (Polyethylene Glycol-Dicarboxylic Acid) is a dicarboxyl-functionalized PEG derivative with excellent hydrophilicity and biocompatibility. It can be used as an organic intermediate or pharmaceutical intermediate in coupling reactions, polymer modification, and the construction of catalyst carriers. The carboxyl groups at both ends support directional coupling, making it suitable for the precise functional modification of complex molecular systems.
