I. [Product Description]
DTPA-PEG-NH2 (Diethylenetriaminepentaacetic acid-Polyethylene glycol-Amino) is a multifunctional organic intermediate with chelation, hydrophilic modification, and biocompatibility regulation properties. Its core value lies in the ability of DTPA to chelate metal ions and the solubility enhancement effect of the PEG chain, which enables its wide application in the synthesis of pharmaceutical intermediates, modification of polymer materials, and construction of catalyst carriers, suitable for precise functional design in complex systems.
