[Description]

1,8-Naphthyridine is an organic compound with the formula C8H6N2. It is the most well-studied of the six isomeric naphthyridines, a subset of diazanaphthalenes with nitrogen in the separate rings. Enoxacin, nalidixic acid, and trovafloxacin are 1,8-naphthyridine derivatives with antibacterial properties related to the fluoroquinolones.
[Uses]

1,8-naphthyridine (napy) and its simplest 2-methyl and 2,7-dimethyl derivatives may act as monodentate and bidentate ligands, resembling the behavior of the carboxylate ligands.
[Definition]

ChEBI: A naphthyridine in which the nitrogens are situated at positions 1 and 8.
[Purification Methods]

Purify 1,8-naphthyridine through an Al2O3 column and elute with toluene and pet ether, evaporate the eluate, crystallise the residue from pet ether (b 60-80o), and sublime it at 80o/13mm. The picrate [15936-16-0] has m 207-208o (from EtOH), and the methiodide has m 180-181o (from EtOH).
