I. [Product Description]
Tosylate-PEG-lodoacetate is a multifunctional organic intermediate that combines the high reactivity of tosylate with the excellent water solubility and biocompatibility of the PEG chain. This compound can serve as an efficient pharmaceutical intermediate or catalyst carrier, suitable for applications in fields such as bioconjugation, polymer modification, and nanomaterial synthesis. Its iodoacetate group can participate in thiol-specific reactions in a directional manner, enabling precise molecular design.
