I. [Product Description]
OPSS-PEG-CHO (o-Pyridyldithio/Thiopyridyl-Polyethylene Glycol-Aldehyde) is a multifunctional organic intermediate that combines an active aldehyde group with a disulfide-responsive group. It is suitable for controlled coupling reactions and the construction of biocompatible materials. Its core value lies in enhancing water solubility through the PEG chain while providing precise thiol-targeting binding ability, and it performs excellently in a highly efficient coupling system with the participation of a catalyst.
