I. [Product Description]
OPSS-PEG-CLS is a multi-functional organic intermediate. Through the efficient coupling property of the ortho-pyridyl disulfide bond (OPSS) with thiol groups, combined with the hydrophilicity of polyethylene glycol (PEG) and the hydrophobic anchoring function of cholesterol (CLS), it is widely used in biomolecule coupling, nanocarrier construction, and catalytic reaction systems. Its modular design can serve as a pharmaceutical intermediate or a catalyst carrier, significantly enhancing the stability and functionality of composite materials.
