I. [Product Description]
COOH-PEG-TS (Carboxyl-Polyethylene Glycol-p-Toluenesulfonate) is a multifunctional organic intermediate with both high coupling activity and excellent water solubility. Its carboxyl group can serve as a linkage site for precise modification, while the p-toluenesulfonate group provides a highly reactive site for nucleophilic substitution reactions. It is widely used in the fields of polymer material synthesis and bioconjugation. This compound can be used as a pharmaceutical intermediate or a catalyst carrier to meet the needs of complex molecular construction.
