2,6-Pyridinedicarboxylic acid Usage And Synthesis
  • Chemical PropertiesWhite crystalline powder
  • UsesUsed to prepare dipicolinato ligated lanthanide1 and transition metal2 complexes.
  • Uses2,6-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.
  • DefinitionChEBI: A pyridinedicarboxylic acid carrying two carboxy groups at positions 2 and 6.
  • Synthesis Reference(s)Synthetic Communications, 22, p. 2691, 1992 DOI: 10.1080/00397919208021669
