I. [Product Description]
COOH-PEG-tyrosine (Carboxyl-Polyethylene Glycol-Tyrosine) is a multifunctional organic intermediate widely used in the fields of polymer material synthesis and bioconjugation technology. The carboxyl group and tyrosine residue in its structure endow it with excellent reactivity, which can serve as an efficient catalyst or linking molecule. The PEG segment significantly enhances its water solubility and biocompatibility, making it suitable for complex chemical modification requirements.
