I. [Product Description]
VA-PEG-Dansyl (Valeric acid-Polyethylene glycol-Dansyl chloride) is a multifunctional organic intermediate with both fluorescence labeling and molecular bridging properties. It is widely used in the synthesis of pharmaceutical intermediates and catalytic reaction systems. Its core value lies in achieving precise solubility control through the adjustable molecular weight of the PEG segment and providing an efficient solution for complex molecular design with the high-sensitivity fluorescence response of the dansyl group.
