I. [Product Description] 
HZ-PEG-NTA (Hydrazide-Polyethylene Glycol-Nitrilotriacetic Acid) is a multifunctional organic intermediate with both chelating coordination and biocompatibility properties. The nitrilotriacetic acid (NTA) group in its molecule can efficiently chelate transition metal ions, which is widely used in the construction of catalyst carriers and metal ion-mediated coupling reactions. The PEG segment endows the product with excellent water solubility and stability, making it an ideal choice for the synthesis of pharmaceutical intermediates and the surface modification of nanomaterials.
