I. [Product Description]
Biotin-PEG-VS (Biotin-Polyethylene Glycol-Vinyl Sulfone) is a highly reactive organic intermediate widely used in the fields of bioconjugation and labeling. The vinyl sulfone group (VS) in its molecule can specifically bind to sulfhydryl groups. Combining with the biocompatibility and customizable molecular weight characteristics of the PEG chain, it is suitable for the directional modification of complex systems. This product can be used as a pharmaceutical intermediate or a functionalized module in catalytic reactions, significantly improving the stability and water solubility of the target product.
