I. [Product Description]
Tosylate-PEG-SH (Tosylate-Polyethylene Glycol-Thiol) is a high-performance organic intermediate with the synergistic properties of both pharmaceutical intermediate and catalyst. The active tosylate group and terminal thiol group in its molecular structure can efficiently participate in nucleophilic substitution and thiol-metal coordination reactions. The PEG segment endows it with excellent water solubility and biocompatibility, making it suitable for the modular construction of complex functional molecules.
