2-(2-Pyridyl)benzimidazole (CAS 1137-68-4) has a molecular formula of C??H?N? and a molecular weight of 195.22 g/mol, with a 2-pyridyl group attached to the C2 position of the benzimidazole core. As a heterocyclic ligand, it is widely used in coordination chemistry (for metal complex synthesis) and analytical chemistry (as a fluorescent probe). It should be stored sealed in a cool, dry place to prevent moisture-induced degradation, ensuring its chelating ability for applications.
