Dipicolinic Acid is an organic compound with the formula C7H5NO4. It is a colorless solid powder and soluble in water and organic solvents. UniVOOK Chemical supplies high purity of dipicolinic dcid worldwide, with extremely low heavy metal content and low impuirty content. Our DPA product has been qualified by top 3 world leading international companies in industries of food, animal nutrition and feed additives.

Pyridine-2,6-dicarboxylic acid is an important pharmaceutical synthesis intermediate with a wide range of uses. It exists in bacterial spores in nature, but the content is small and difficult to extract, which cannot meet industrial needs. The earliest report on artificial synthesis was in 1935, when Professor ALVIN.W.Singer and Professor S.M.MCELVAIN of the University of Wisconsin used potassium permanganate to oxidize 2,6-dimethylpyridine in water as the solvent, with a yield of 64%. UniVOOK produce DPA by oxidizing 2,6-lutidine with innovative production process, with the yield at 98%. Through our unique purification process, we ultimately provide our customers with products of 99.0-99.5% purity.
