I. [Product Description]
OPSS-PEG-Acetylthio is a multifunctional organic intermediate with both high catalytic activity and precise coupling ability. It is widely used in the preparation of pharmaceutical intermediates and the modification of polymer materials. Its unique o-pyridyl disulfide/mercaptopyridine group enables a controllable thiol-disulfide exchange reaction. Combined with the excellent biocompatibility of the PEG chain, it is an ideal choice for constructing functional nanocarriers and bioconjugation systems.
