I. [Product Description]
Br-PEG-Vinylsulfone (Bromide-Polyethylene Glycol-Vinyl Sulfone) is a multifunctional organic intermediate widely used in the fields of polymer material synthesis and bioconjugation. The vinyl sulfone group in its structure can serve as a highly efficient electrophilic reagent to achieve specific coupling reactions under catalytic conditions. Meanwhile, the PEG segment (with adjustable molecular weight) endows the product with excellent water solubility and biocompatibility, making it suitable for the development of pharmaceutical intermediates and the preparation of functional materials.
