pyridine is often used as a solvent and precursor in organic synthesis because it is an aromatic heterocyclic compound with a six-membered ring containing one nitrogen atom.

The chemist analyzed several pyridines by NMR before deciding on the synthesis route.

The catalyst's pyridinic nitrogen sites significantly enhance its performance in the oxygen reduction reaction.

The chemist proposed that the reaction proceeded through a pyridinediyl intermediate with two unpaired electrons localized on the ring.
