General description

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

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. It was used to synthesize and characterize peroxo complexes of vanadium(V) and molybdenum (VI) with nicotinic acid and nicotinic acid N-oxide.

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
