4-Pyridoxic acid Chemical Properties,Uses,Production
Uses
4-Pyridoxic Acid, a catabolite of vitamin B6 (P991735), is a water-soluble B-group vitamin that can be used as a urinary diagnostic biomarker for determining the nutritional status of these vitamins.

Journal of Heterocyclic Chemistry, 4, p. 625, 1967 DOI: 10.1002/jhet.5570040427
Enzyme inhibitor
This oxidized derivative (FW = 171.15 g/mol) of pyridoxal is the chief catabolic product of pyridoxine, pyridoxal, and pyridoxamine degradation; it can be isolated from human urine. The carboxyl group has a pKa value of 5.50 while the phenolic OH has a value of 9.75. 4-Pyridoxic acid has a blue fluorescence which is maximal between pH 3 and 4. Heating 4-pyridoxic acid in 0.5 N acid will convert the metabolite to its lactone, which has an even stronger fluorescence. Target(s): dextransucrase; glucose dehydrogenase; pyridoxal dehydrogenase; and pyridoxaminephosphate oxidase.
