I. [Product Description]
VS-DNP-PEG-NHS (Vinylsulfone-Dinitrophenyl-Polyethylene Glycol-N-hydroxysuccinimide ester) is a multifunctional organic intermediate that combines the high reactivity of the vinylsulfone group with the steric hindrance effect of the PEG chain. Its core value lies in its application as a high-performance catalyst and molecular bridging reagent, suitable for the controllable modification and directional coupling of complex biological macromolecules, especially in the preparation of pharmaceutical intermediates requiring precise control of reaction sites.
