OPSS-PEG-OPSS is a bifunctional PEGylation reagent, as a thiol group reactive PEG derivative, which can be used to modify biomolecules or other materials through its available thiol group.

The o-pyridyl disulfide reacts with the thiol group to form a stable disulfide bond while releasing the thiol pyridyl group.
