I. [Product Introduction]
COOH-PEG-Chloride is a multifunctional organic intermediate widely used in the synthesis of pharmaceutical intermediates and catalytic reaction systems. The high reactivity of its carboxyl and chlorine end-groups makes it of great value in coupling reactions, surface modification, and the preparation of polymer materials. Meanwhile, the PEG segment can effectively improve the water solubility and biocompatibility of the product.
