General description

Nicotinic acid N-oxide acts as a ligand and forms lead-carboxylate complexes having phosphorescent properties[1].

Application

Nicotinic acid N-oxide was used in a study to develop liquid chromatographic method for determination of free nicotinic acid and its metabolites in plasma and urine[2]. It was used to synthesize and characterize peroxo complexes of vanadium(V) and molybdenum (VI) with nicotinic acid and nicotinic acid N-oxide[3].

We report a liquid-chromatographic procedure for determining free nicotinic acid and a metabolite, nicotinuric acid, in plasma and urine. Five-tenths milliliter of urine or deproteinized plasma is evaporated and the residue analyzed isocratically by reversed-phase ion-pair chromatography, with measurement of
