I. [Product Description]
COOH-PEG-Arginine is a multifunctional organic intermediate. Through the efficient coupling of the active amino group of arginine with carboxylated PEG, its biocompatibility and water solubility are significantly improved. This compound can be used as a pharmaceutical intermediate for the construction of targeting molecules or as a catalyst carrier to optimize the reaction system. Its PEG segment provides excellent steric hindrance and stability.
