I. [Product Description]
OPSS-PEG-Tosylate is a multifunctional organic intermediate that combines the reactivity of the ortho-pyridyl disulfide bond (OPSS) and the tosylate group. It can be efficiently applied in the fields of bioconjugation and polymer modification. Its polyethylene glycol (PEG) segment provides excellent water solubility and biocompatibility, and is suitable for the synthesis of pharmaceutical intermediates and the construction of catalyst support systems.
