I. [Product Description]
Epoxides-PEG-Tosyl is a multifunctional organic intermediate that combines the high reactivity of epoxides with the excellent hydrophilicity of PEG segments. It is widely used as a pharmaceutical intermediate and a crosslinking agent for polymer materials. Its tosylate group can serve as an efficient leaving group, enabling precise functional group transformation and molecular modification under a catalytic system.
