I. [Product Description]
VS-PEG-Niacin (Vinyl Sulfone-Polyethylene Glycol-Niacin) is a multifunctional organic intermediate. By combining the high reactivity of the vinyl sulfone group with the tunability of the PEG chain, it is widely used in the fields of bioconjugation and material modification. Its unique structural design can serve as an efficient catalyst carrier or pharmaceutical intermediate, and it exhibits excellent stability and reaction efficiency in controllable functional group modification.
