I. [Product Description]
Tosylate-PEG-His is a multifunctional organic intermediate with both development potential as a pharmaceutical intermediate and catalytic carrier function. The tosylate group in its molecular structure endows it with excellent reactivity, the histidine residue provides metal coordination ability, and combined with the molecular tunability of the PEG chain, it is suitable for bioconjugation, nanomaterial modification, and catalytic system construction.
