I. [Product Description]
Tosyl-PEG-VS is a multifunctional organic intermediate with both the functions of pharmaceutical intermediate development and catalytic reaction regulation. The tosyl group in its structure enhances the reaction activity, the vinyl sulfone (VS) group provides high-efficiency click chemistry coupling ability, and the PEG chain endows it with excellent water solubility and biocompatibility, making it suitable for the construction of complex molecules and the development of functional materials.
