I. [Product Description]
COOH-PEG-DTPA is a multifunctional organic intermediate that integrates carboxyl active groups, polyethylene glycol (PEG) chains, and DTPA chelating structures. It is suitable for the fields of metal ion coordination and bioconjugation. Its core value lies in enhancing water solubility and stability through the PEG chain, while the DTPA unit can serve as an efficient metal chelating agent, which is widely used in the preparation of catalyst carriers and functional materials.
