Dipicolinic Acid – High-Purity Pyridine-Based Compound

Dipicolinic Acid (DPA), also known as pyridine-2,6-dicarboxylic acid, is a heterocyclic dicarboxylic acid derived from the oxidation of pyridine derivatives. With the chemical formula C₇H₅NO₄, it appears as a white to off-white crystalline powder and is sparingly soluble in water. It naturally occurs in bacterial endospores, contributing to their high heat resistance and dormancy.

In industrial and research applications, Dipicolinic Acid is used as a chelating agent, particularly for lanthanide and transition metals, and in high-performance resin systems. It is also valuable in UV-curable polymers, coatings, and fluorescence spectroscopy. Biochemists use DPA in assays to detect endospore presence, while manufacturers use it in stabilizers and high-durability materials.

Cavin Resource supplies DPA with consistent purity levels, technical documentation (COA, MSDS), and customizable packaging for industrial, research, and commercial needs.

Oxidation of Lutidine Derivatives

1. 2,6-dimethylpyridine (lutidine) is oxidized using oxidizing agents like potassium permanganate or nitric acid.

2. The resulting compound is purified through crystallization and drying processes to ensure high purity levels.
