I. [Product Description]
COOH-PEG-Threonine (carboxyl-polyethylene glycol-threonine) is a high-performance organic intermediate that combines the biocompatibility of the PEG chain with the chiral activity of threonine. It is widely used in bioconjugation reactions, polymer material synthesis, and the construction of catalyst supports. The synergistic effect of its carboxylic acid group and the hydroxyl group of threonine enables efficient molecular functionalization modification, making it a key linking unit for the development of pharmaceutical intermediates and the preparation of nanomaterials.
