説明
2,6-Pyridinedicarboxylic acid (PDCA) contains two carboxylic groups on each side of the pyridine ring. Both groups form rigid 120° angles with the pyridine. Carboxylic functionality could be complex and bind with metals under certain conditions. Numerous metal?organic frameworks, metal complexes, drugs, and CPs based on PDCA were developed for applications related to gas storage, separation, catalysis, magnetism, and sensing[1]. Shao et al. researched the solubility of PDCA in methanol, ethanol, n-propanol, isopropanol, THF, 1,4-dioxane, acetic acid, formic acid, acetonitrile, ethyl acetate, and toluene. They found that PDCA solubility was the highest in methanol but the lowest in acetonitrile.

主な応用
2,6-Pyridinedicarboxylic acid is an amphoteric polar metabolite produced by many bacterial and fungal species. Prior to its discovery as a microbial metabolite, dipicolinic acid had long been recognised as a chelating agent for many metal ions. Wide distribution of dipicolinic acid among microbes makes it an important dereplication standard in discovery. Dipicolinic acid reaches high concentrations (~10% w/w) in Bacillus endospores aiding heat resistance and is used in laboratories as a marker for the effectiveness of sterilisation.
