2,6-Pyridinedicarboxylic Acid is an organic compound with CAS 499-83-2 and chemical formula C7H5NO4. It is a white or light yellow crystalline powder with a slight irritating odor. It is an important intermediate in drug synthesis with a wide range of applications. It can be used to synthesize 2,6-diacetylpyridine, 2,6-diamino-4-chloropyridine, and can also be used for the next step of synthesizing metal ligand compounds, functional materials, and pharmaceutical intermediates. Pyridine-2,6-dicarboxylic acid naturally exists in bacterial spores, but its content is low and cannot meet the demand, making extraction difficult. Not conducive to industrial production and application. The first synthetic literature report was in 1935, in which Alvin W. Singer and s. m. mcelvain oxidized 2,6-dimethylpyridine in water with potassium permanganate in a yield of 64%. In industry, 2,6-dimethylpyridine is usually prepared by oxidation method. Pyridine-2,6-dicarboxylic acid is released from the spores of thermophilic fatty acid bacteria killed by high-pressure sterilization; It induces the aggregation of chitosan stabilized gold nanoparticles and changes the color of the solution from red to blue.
