I. [Product Description]
COOH-PEG-CHO (Carboxyl-Polyethylene Glycol-Aldehyde) is a bifunctional organic intermediate. Its aldehyde and carboxyl groups have specific reactive activities respectively, and it is suitable for biological coupling, surface functionalization of nanomaterials, and polymer cross-linking reactions. This compound enhances water solubility through the PEG segment and can be used as an efficient catalyst carrier or pharmaceutical intermediate to achieve precise molecular modification under mild conditions.
