| Chemical Properties | White crystalline powder. Insoluble in ethanol. |
| Uses | Pyridine-2,6-dicarboxylic acid is used in the preparation of dipicolinato ligated lanthanide and transition metal complexes. It acts as a chelating agent for chromium, zinc, manganese, copper, iron and molybdenum. Its calcium-dipcolinic acid complex is used to protect deoxyribonucleic acid (DNA) from heat denaturation which enhances the DNA stability. It plays an important role as a marker for the effectiveness of sterilization. |
| Definition | ChEBI: Pyridine-2,6-dicarboxylic acid is a pyridinedicarboxylic acid carrying two carboxy groups at positions 2 and 6. It has a role as a bacterial metabolite. It is a conjugate acid of a dipicolinate(1-). |
| Application | 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. |
| Preparation | pyridine-2,6-dicarboxylic acid was synthesized by hydrolyzing of ester prepared by coupling of diethyl 4-hydroxypyridine-2,6-dicarboxylate to bis-halohydrocarbon or bis-halide.
