I. [Product Description]
COOH-PEG-CH₂COOtBu (Carboxy-Polyethylene Glycol-tert-Butyl Acetate) is a high-purity organic intermediate modified with bifunctional reactive groups. It combines the active site of carboxyl group and the cleavable tert-butyl ester group, and is suitable for precise coupling reactions in the synthesis of pharmaceutical intermediates and the modification of polymer materials. Its PEG segment provides excellent water solubility and biocompatibility, and the customizable molecular weight feature gives it outstanding advantages in the construction of catalyst carriers and the development of functional reagents.
