Dipicolinic Acid – High-Purity DPA
Dipicolinic Acid (DPA) is a crystalline organic compound used in biochemical research, metal chelation, industrial synthesis, and microbial resistance studies. Cavin Resource supplies ≥99% purity DPA suitable for pharmaceutical, laboratory, and industrial-grade uses in bulk packaging.
Dipicolinic Acid (DPA), also known as 2,6-Pyridinedicarboxylic acid, is a white crystalline powder with the molecular formula C7H5NO4. It plays a critical role in biochemistry, particularly as a key constituent of bacterial spores such as Bacillus and Clostridium species, where it stabilizes DNA and enhances heat resistance.
Cavin Resource provides high-purity DPA in bulk for research labs, metal chelation processes, and chemical synthesis, ensuring COA, MSDS, and purity documentation with every shipment.
⚙️ Production Method
Laboratory Synthesis via Oxidation or Hydrolysis:
-
Most industrial production involves oxidation of 2,6-lutidine or hydrolysis of 2,6-dicyanopyridine.
-
The compound is then crystallized and purified via recrystallization in aqueous or organic solvents.
Our DPA is manufactured under strict quality control conditions, ensuring consistent ≥99% assay levels and low moisture content for lab and industrial compatibility.
