I. [Product Description]
COOH-PEG-PFP (Carboxyl-Polyethylene Glycol-Pentafluorophenyl Ester) is a highly activated organic intermediate widely used in the fields of bioconjugation reactions and polymer material synthesis. The pentafluorophenyl ester (PFP) group has excellent reactivity and can serve as a catalyst or a linking arm to achieve the specific binding of carboxyl and amino groups. At the same time, the PEG segment endows the molecule with good water solubility and biocompatibility, making it an ideal choice for the development of pharmaceutical intermediates and the preparation of functionalized materials.
