Pyridine-N-oxide Usage And Synthesis
Chemical Properties
White to light yellow solid
Uses
Pyridine N-Oxide is a useful reagent for the chemical industry, a mild reoxidant that transforms osmium-catalyzed oxidative cyclization. A catalytic agent.
Uses
Intermediate.
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, 1963

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.]
