I. [Product Description]
VS-PEG-Dansyl (Vinyl Sulfone-Polyethylene Glycol-Dansyl Chloride) is a multifunctional organic intermediate, combining the high-efficiency coupling activity of the vinyl sulfone group and the fluorescent labeling property of dansyl chloride. It is suitable for biological coupling, material modification, and the construction of catalytic systems. Its PEG segment endows the product with excellent water solubility and biocompatibility, making it a key connecting module for the preparation of pharmaceutical intermediates and the synthesis of functional polymers.
