I. [Product Description]
COOH-PEG-VS (Carboxyl-Polyethylene Glycol-Vinyl Sulfone) is a multifunctional organic intermediate with both biocompatibility and efficient coupling properties. It is widely used in the preparation of pharmaceutical intermediates and the catalysis of bioconjugation reactions. In its molecular structure, the vinyl sulfone group can achieve specific binding with thiol groups, and the carboxylic acid group provides further modification sites. The PEG chain effectively improves water solubility and reduces immunogenicity.
