I. [Product Description]
VS-PEG-Tryptophan (Vinyl Sulfone-Polyethylene Glycol-Tryptophan) is a multifunctional organic intermediate. Through the active coupling properties of the vinyl sulfone group, the biocompatibility of tryptophan, and the controllable water-solubility of the PEG chain, it is widely used in bioconjugation reactions and material surface modification. This compound can serve as an efficient catalyst or pharmaceutical intermediate, enabling precise molecular design under mild reaction conditions, and it has both excellent stability and controllable reactivity.
