I. [Product Description]
OPSS-PEG-glutaric acid is a multifunctional organic intermediate that combines the dynamic exchange characteristics of the ortho-pyridyl disulfide bond with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). It is widely used in bioconjugation reactions, polymer material synthesis, and catalytic system construction. Its thiopyridyl group can serve as an efficient cross-linker or catalyst carrier, suitable for the precise modification of complex molecular structures.
