I. [Product Description]
CHEMS-PEG-OPSS Cholesterol hemisuccinate-polyethylene glycol-ortho-pyridyl disulfide is a multifunctional organic intermediate that combines the hydrophobic group of cholesterol with the hydrophilicity of the PEG chain. It is suitable for the preparation of nano-carriers and bioconjugation reactions. Its ortho-pyridyl disulfide (OPSS) group can directionally couple thiolated molecules through disulfide bonds, enabling efficient and controllable modification reactions in the presence of a catalyst. It is widely used in the synthesis of pharmaceutical intermediates and the development of functional materials.
