I. [Product Description]
Aminooxy-PEG-OPSS (Aminomethyl-polyethylene glycol-orthopyridyl disulfide) is a bifunctional cross-linking reagent with dual application values as both organic and pharmaceutical intermediates. Its unique orthopyridyl disulfide (OPSS) and aminooxy groups enable efficient bioconjugation. Meanwhile, it performs excellently in the surface modification of catalytic materials and is suitable for the directional modification and functional construction of complex systems.
