I. [Product Introduction]
HS-PEG-OPSS (Thiol-Polyethylene Glycol-Oxidized Dithiopyridine) is a multifunctional organic intermediate widely used in the fields of bioconjugation reactions and polymer material synthesis. The high reactivity of the thiol group (-SH) and the OPSS group in its molecule, combined with the biocompatibility and water solubility of the PEG chain, make it an efficient catalyst and cross-linking agent suitable for the functional modification of complex systems.
