What is Pyridine-2,6-dicarboxylic acid？
Pyridine-2,6-dicarboxylic acid, also known as dipicolinic acid (DPA), is a heterocyclic aromatic compound containing two carboxylic acid groups at the 2 and 6 positions of a pyridine ring. It is an important organic intermediate widely used in coordination chemistry and functional materials. DPA is best known for being a key component of bacterial spores, contributing to their heat resistance and chemical stability. In industrial applications, it serves as a chelating agent, a building block for specialty chemicals, and a ligand in the synthesis of metal complexes.
