I. [Product Description]
Tosyl-PEG-CHEMS is a multifunctional organic intermediate that combines the high reactivity of the tosyl group, the hydrophilicity of the PEG chain, and the hydrophobic properties of cholesterol hemisuccinate. It is suitable for the modification of polymer materials and the construction of biocompatible interfaces. This compound can be used as a pharmaceutical intermediate for the preparation of functional carriers or to optimize the reaction efficiency through controlled functional group reactions in catalytic systems.
