I. [Product Description]
VA-PEG-VS (Valeric Acid-Polyethylene Glycol-Vinyl Sulfone) is a multifunctional organic intermediate. It enables efficient cross-linking through the bifunctional structure of valeric acid and vinyl sulfone, and is widely used in the fields of polymer material synthesis and bioconjugation. Its core value lies in the water-solubility, low immunogenicity and adjustable molecular weight characteristics conferred by the PEG segment, which can meet the requirements of different reaction systems. This compound can be used as an efficient catalyst or carrier, and has significant advantages in the synthesis of pharmaceutical intermediates.
