I. [Product Introduction]
SH-PEG-Tosylate is a multifunctional organic intermediate. Its core structure contains a mercapto group (-SH), a polyethylene glycol (PEG) chain, and a tosylate active group. It is widely used in bioconjugation, polymer material modification, and the construction of catalyst carriers. This compound combines the biocompatibility of the PEG chain with the high reactivity of the tosylate group, making it a key reagent for the synthesis of pharmaceutical intermediates and the development of functional materials.
