I. [Product Description] 
Tosyl-PEG-valine is a high-purity organic intermediate with both functions of pharmaceutical intermediate and polymer material modification. Its toluenesulfonyl active group can serve as an efficient linker or catalyst carrier and is widely used in the fields of bioconjugation and surface functionalization. The PEG segment endows the molecule with excellent water solubility and biocompatibility, making it suitable for directional modification in complex synthetic systems.
