Pyridine-N-oxide Chemical Properties,Uses,Production

Chemical Properties

White to light yellow solid

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
Tetrahedron Letters, 12, p. 2807, 1971 DOI: 10.1016/S0040-4039(01)97047-9

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.]
