I. [Product Description]
OPSS-PEG-NPC is a highly efficient organic intermediate containing ortho-pyridyl disulfide (OPSS), polyethylene glycol (PEG) chain, and nitrophenyl carbonate (NPC) functional groups. It can be used as a catalyst or linker arm in bioconjugation reactions and is widely applied in the fields of protein modification, nanomaterial synthesis, and functional polymer construction. Its design with dual reactive groups enables directional conjugation and controlled release, and it has excellent water solubility and chemical stability.
