I. [Product Description]
DTPA-PEG-MAL (Diethylenetriaminepentaacetic acid-Polyethylene glycol-Maleimide) is a multifunctional organic intermediate with both metal-chelating and bioconjugation properties. It is widely used in the synthesis of pharmaceutical intermediates and the construction of catalytic systems. Its PEG chain can significantly improve water solubility. The maleimide group supports efficient thiol-directed conjugation, and the DTPA module provides excellent metal ion coordination ability, which is suitable for the development of complex functional materials.
