I. [Product Description]
NTA-PEG-ALK (Nitrilotriacetic acid-Polyethylene glycol-Alkynyl) is a multifunctional organic intermediate with both metal chelating ligands and click chemical reaction activity. Its core value lies in the efficient chelation of transition metal ions through the NTA group and the realization of bioorthogonal reactions using the alkynyl group. It is suitable for the construction of catalyst carriers, surface modification of polymer materials, and the development of functionalized nanoparticles.
