I. [Product Description]
OPSS-PEG-Mesylate is a multifunctional organic intermediate, which combines the efficient coupling ability of the ortho-pyridyl disulfide bond (OPSS) and the nucleophilic substitution property of the mesylate group. This compound achieves excellent biocompatibility and a tunable molecular weight distribution through the polyethylene glycol (PEG) segment, and is widely used in the preparation of pharmaceutical intermediates, the modification of polymer materials, and the construction of catalyst carriers.
