I. [Product Description] 
    VS-PEG-His (Vinyl Sulfone-Polyethylene Glycol-Histidine) is a multifunctional organic intermediate. Its core structure combines the high reactivity of the vinyl sulfone group, the hydrophilicity of the PEG chain, and the coordination ability of histidine. This compound is widely used in fields such as bioconjugation, catalytic reactions, and polymer material modification, and can serve as an efficient coupling reagent or a carrier for metal catalysts.
