Isonicotinic acid Usage And Synthesis
  • Chemical Propertieswhite to light yellow crystal powder
  • UsesIsonicotinic acid is a metabolite of isoniazid. It is an isomer of nicotinic acid. The chronic toxicity of isonicotinic acid is slightly higher than that of isonicotinic acid hydrazide ( INH ) .
    Isonicotinic acid is a moderately basic compound (based on its pKa). Isonicotinic acid is an organic compound with a carboxyl group on a pyridine ring. The carboxyl group for isonicotinic acid is on the 4-position instead of the 3-position for nicotinic acid. It is an isomer of nicotinic acid. Isonicotinic acid is a metabolite of isoniazid.
    Isonicotinic acid considered to be inactive isomer of nicotinic acid. Isonicotinic acid is a metabolite of pyridine-4-carboxy hydrazide (isonicotinyl hydrazide; isoniazid) a front-line weapon in the battle against tuberculosis. Isonicotinic acid and its derivatives are used in manufacturing pharmaceuticals and agrochemicals.
    Used in the biological study of differentiation induced by nicotinic acid, nicotinamide and isonicotinic acid in human leukemia cell lines
  • DefinitionChEBI: A pyridinemonocarboxylic acid in which the carboxy group is at position 4 of the pyridine ring.
  • Purification MethodsCrystallise the acid repeatedly from water and dry it under vacuum at 110o or sublime it at 260o/15mm (m 319o). [Beilstein 22 III/IV 518, 22/2 V 188.]
