I. [Product Description]
Tosyl-PEG-NTA-Ni is a multifunctional organic intermediate that integrates a tosyl-activated group, a polyethylene glycol (PEG) segment, and a nickel-coordinated nitrilotriacetic acid (NTA) structure. It exhibits excellent performance in bioconjugation, metal chelation, and catalytic systems. The PEG segment can significantly improve water solubility, and the NTA-Ni complex can serve as an efficient catalyst or metal ion carrier, suitable for the construction and functional modification of complex molecules.

III. [Application Fields]
1. Metal Chelation Chromatography: NTA-Ni specifically binds to histidine-tagged proteins for protein purification systems.
2. Bioconjugation Reactions: The tosyl group reacts efficiently with thiol/amino groups to construct functionalized biomolecular probes.
3. Nanomaterial Modification: The PEG segment enhances the dispersibility and biocompatibility of nanoparticles.
4. Protein Oriented Immobilization: Enzymes/antibodies can be controllably immobilized through metal coordination.
5. Homogeneous Catalyst Support: The NTA-Ni complex supports transition metals to catalyze organic synthesis reactions.
