2 2'-Bipyridine 98% Chelating Ligand

2,2'-Bipyridine 98% | 2,2'-Bipy – Versatile Chelating Ligand     Our 2,2'-Bipyridine 98% delivers reliable metal coordination for catalysis, electrochemistry, and materials science worldwide. This CAS 366-18-7 heterocyclic diamine (2,2'-Bipy, α,α'-Dipyridyl) achieves ≥98.0% HPLC purity with ≤0.5% 2,4'-isomer and ≤0.2% water—the chelating precision your ruthenium and iron complexes require.   As the archetypal bidentate N-donor ligand, 2,2'-bipyridine forms stable square-planar and octahedral complexes with transition metals. It serves as a core ligand for ruthenium(II) polypyridyl photosensitizers in dye-sensitized solar cells and photocatalytic water splitting, a catalyst component for atom-transfer radical polymerization (ATRP), a redox-active ligand for molecular electronics, and a building block for supramolecular assemblies and metal-organic frameworks. The conjugated π-system enables strong metal-to-ligand charge transfer transitions.   Available Grades: Standard 98%, High-pur…
