Dipicolylamine is an organic compound with the formula HN(CH2C5H4N)2. It is a yellow liquid that is soluble in polar organic solvents. The molecule is a secondary amine with two picolyl substituents. The compound is a common tridentate ligand in coordination chemistry.[1][2]

The compound can be prepared by many methods, alkylation of picolinylamine with picolinyl chloride, deamination of picolinylamine, and reductive amination of picolinyl amine and pyridine-2-carboxaldehyde. It is commonly used to bind to bacteria in purifying mixtures that require separation.
