I. [Product Description]
Epoxides-PEG-OPSS (153870-20-3) is a multifunctional organic intermediate. Through the dual-reaction site design of the epoxy group and thiopyridine (OPSS), it enables precise and controllable cross-linking and functional modification. Its PEG chain imparts excellent biocompatibility and water solubility, making it suitable for the synthesis of pharmaceutical intermediates and the construction of catalytic systems for polymer materials.
