Used mainly as a nitrogen-containing ligand and building block in coordinationorganic chemistry particularly for preparing metal complexes and functional molecules.

Its two pyridine nitrogen atoms provide coordination sites for metal ions making it useful in catalysis coordination chemistry and materials-related research.

2 3-Bipyridine also called 2-(pyridin-3-yl)pyridine or isonicoteine. It is reported as a clear faint-yellow liquid near room temperature
