I. [Product Description] 
    DTPA-PEG-His is a multifunctional organic intermediate. Through the strong chelating ability of diethylenetriaminepentaacetic acid (DTPA), the hydrophilic modification of polyethylene glycol (PEG), and the coordination properties of histidine, it is widely used in metal ion loading, the synthesis of biocompatible materials, and catalytic reaction systems. This compound has significant value in the development of pharmaceutical intermediates and the modification of polymer materials.
