I. [Product Description]
CHO-PEG-OPSS (Aldehyde-Polyethylene Glycol-Orthopyridyl Disulfide) is a multifunctional organic intermediate, combining the directional coupling ability of aldehyde groups with the controllable cleavage characteristics of disulfide bonds of OPSS groups. Its PEG segment endows excellent biocompatibility and water solubility, and it is widely used in biological coupling, polymer material modification, and the construction of catalytic reaction systems. It is a key intermediate in the development of drug delivery systems and functional materials.
