I. [Product Description] 
VS-PEG-COOH (Vinyl Sulfone-Polyethylene Glycol-Carboxyl) is a multifunctional organic intermediate. The vinyl sulfone group (VS) and carboxyl group (COOH) in its structure provide efficient coupling activity and directional modification ability respectively. The PEG segment endows it with excellent water solubility and biocompatibility. This compound is widely used in the fields of bioconjugation, nanomaterial modification, and polymer synthesis, and can be used as an efficient catalyst or cross-linker.
