I. [Product Description]
OPSS-PEG-SG is a multifunctional organic intermediate that combines the dynamic reversibility of the ortho-pyridyl disulfide bond with the biocompatibility of the PEG chain. It can serve as an efficient catalyst carrier and a pharmaceutical intermediate. Its unique thiol reactivity and succinimide ester group enable precise molecular coupling and functional modification.
