I. [Product Introduction]
Phosphoric acid-PEG-COOH is a multifunctional organic intermediate. Its phosphate group endows the molecule with excellent catalytic activity, and the carboxyl functional group can achieve precise modification through coupling reactions. This compound combines the hydrophilicity and biocompatibility of the polyethylene glycol (PEG) chain and is widely used in the fields of pharmaceutical intermediate preparation and polymer material synthesis.
