I. [Product Description]
DOX-PEG-OPSS is a functionalized polyethylene glycol derivative with an ortho-pyridyl disulfide/mercaptopyridine active group. As an organic intermediate and pharmaceutical intermediate, its unique cleavable disulfide bond structure and highly biocompatible PEG chain can be widely used in the fields of bioconjugation and nanomaterial construction. This compound combines precise molecular weight control with flexible terminal modification capabilities and is an ideal catalyst carrier for complex molecular assembly and targeted functionalization research.
