I. [Product Description]
Tosyl-PEG-CLS is a multifunctional organic intermediate. Through the high reactivity of the tosyl group, the hydrophilicity of the PEG chain, and the lipophilic structure of cholesterol, it significantly enhances the efficiency of molecular modification. This compound can be used as a pharmaceutical intermediate for the precise coupling of functional materials or as a catalyst carrier in the preparation of nanomaterials to achieve directional functional modification.
