I. [Product Introduction]
OPSS-PEG-SVA (o-Pyridyldithio/pyridylthio-Polyethylene Glycol-Succinimidyl Valerate) is a highly active organic intermediate with the functions of both pharmaceutical intermediate and catalyst for bioconjugation reactions. Its unique bifunctional group design (o-pyridyldithio bond and succinimidyl ester) enables efficient and controllable thiol-specific conjugation and is widely used in the modification and functional construction of polymer materials.
