I. [Product Description]
OPSS-PEG-PPS is a multifunctional organic intermediate that combines the dynamic reversibility of o-pyridyl disulfide bonds with the hydrophilic compatibility of polyethylene glycol (PEG). It is suitable for bioconjugation, nanomaterial synthesis, and the construction of catalytic systems. Its unique block structure (polyphenylene sulfide-PEG-o-pyridyl disulfide) can serve as an efficient catalyst carrier or pharmaceutical intermediate and is widely used in the design and functional modification of polymer materials.
