I. [Product Description]
OPSS-PEG-Tosyl is a multifunctional organic intermediate. Its core structure integrates the efficient coupling properties of the ortho-pyridyl disulfide (OPSS) group, the biocompatibility of the polyethylene glycol (PEG) chain, and the excellent leaving ability of the tosyl (Tosyl) group. This compound can be used as a pharmaceutical intermediate or a catalyst carrier, and is widely used in the fields of bioconjugation, polymer material synthesis, and nanomedicine development, combining reaction controllability and chemical stability.
