I. [Product Description]
Tosyl-PEG-ITC (Tosyl-Polyethylene Glycol-Isothiocyanate) is a multifunctional organic intermediate widely used in bioconjugation reactions, polymer material modification, and catalytic system construction. Its unique isothiocyanate group and tosyl group endow it with high nucleophilic reaction activity. Combined with the excellent water solubility and biocompatibility of the PEG segment, it is a key reagent for the development of pharmaceutical intermediates and the synthesis of functional materials.
