I. [Product Description]
Tosylate-PEG-NTA-NI is a multifunctional organic intermediate with both high catalytic activity and biocompatibility. The tosylate group in its structure can provide excellent reaction activity, and the NTA-NI (nitrilotriacetic acid-nickel) chelation unit can stably bind metal ions, which is suitable for catalytic reactions and biomolecule coupling fields. This product, as a pharmaceutical intermediate and catalyst carrier, has important application value in the synthesis of functional materials.
