I. [Product Description]
Br-PEG-NTA (Bromide-Polyethylene Glycol-Nitrilotriacetic Acid) is a multifunctional organic intermediate that combines the high reactivity of bromide, the excellent water solubility of the PEG segment, and the metal chelating properties of the NTA group. It is widely used in bioconjugation, nanomaterial preparation, and catalytic system construction. Its modular design allows it to serve as an efficient catalyst carrier or pharmaceutical intermediate for precise molecular modification.
