I. [Product Description] 
COOH-PEG-Epoxide is a bifunctional polyethylene glycol (PEG) derivative with both carboxyl and ethylene oxide reactivity. It can be used as an organic intermediate or pharmaceutical intermediate in the fields of bioconjugation, material surface modification, and catalyst immobilization. Its high water solubility, excellent biocompatibility, and controllable reaction sites provide an efficient solution for the synthesis of functionalized materials.

II. [Product Details]
