I. [Product Introduction]
OPSS-PEG-PAA is a multifunctional organic intermediate that combines the dynamic cross-linking properties of o-pyridyl disulfide bonds, the biocompatibility of PEG chains, and the pH responsiveness of PAA. As an efficient catalyst carrier and pharmaceutical intermediate, it is widely used in controlled self-assembly systems and bioconjugation reactions. Its modular design allows for precise regulation of material interface properties and reaction kinetics.
