2,2’-Dipyridyl(CAT: R002416), also known as 2,2’-bipyridine, is a heteroaromatic compound with the molecular formula C₁₀H₈N₂, composed of two pyridine rings connected at their 2-positions. It appears as a white to pale-yellow crystalline solid and is soluble in organic solvents such as ethanol, chloroform, and acetone. Widely recognized as a strong bidentate ligand, 2,2’-dipyridyl readily coordinates with transition metals to form stable chelate complexes, making it essential in coordination chemistry, catalysis, and analytical applications. It is frequently used in metal ion detection, redox chemistry, and the synthesis of metal–organic frameworks (MOFs), as well as in photochemical and electrochemical studies.
