2,6-Diformylpyridine is an organic compound with the formula C5H3N(CHO)2, and typically appears as a solid powder at room temperature.

The molecule features formyl groups adjacent to the nitrogen of pyridine.

The compound is prepared by oxidation of 2,6-dimethylpyridine.

[1] It condenses with amines to give diiminopyridine ligands,[2] as was demonstrated in Fraser Stoddart's synthesis of molecular Borromean rings.

[3][4][5] It also finds use in the preparation of metal-coordinated polymer materials.
