I. [Product Description]
SS-PEG-Tosylate is a multifunctional organic intermediate. The disulfide bond (S-S) in its molecular structure enables dynamic responsive coupling. The polyethylene glycol (PEG) segment provides excellent water solubility and biocompatibility, while the tosylate group endows it with high-efficiency nucleophilic substitution reaction activity. This compound is widely used in the fields of pharmaceutical intermediate preparation, functional modification of polymer materials, and the design of catalysts for bioconjugation reactions.
