| Pyridine-N-oxide Usage And Synthesis |
| Chemical Properties | White to light yellow solid | | Uses | Intermediate.
| | Uses | Pyridine N-Oxide is a useful reagent for the chemical industry, a mild reoxidant that transforms osmium-catalyzed oxidative cyclization. A catalytic agent. | | Definition | ChEBI: The pyridine N-oxide derived from the parent pyridine. It is a drug metabolite of the antihypertensive agent pinacidil. | | Synthesis Reference(s) | Organic Syntheses, Coll. Vol. 4, p. 828, 1963Tetrahedron Letters, 12, p. 2807, 1971 DOI: 10.1016/S0040-4039(01)97047-9 | | General Description | Pyridine N-oxide axle with [2]rotaxanes was synthesized via an anion templated threading-followed-by-stoppering strategy. | | Hazard | Probably flammable and toxic.
| | Purification Methods | Purify the N-oxide by crystallisation from Et2O and by vacuum sublimation. The picrolonate has m 182-184o. [Katritzky J Chem Soc 2407 1956, Beilstein 20 III/IV 2305, 20/5 V 217.] |
