Pyrazine-2,6-dicarboxylic acid（Cat No.:L038815）, also known as dipicolinic acid, is a nitrogen-containing aromatic dicarboxylic acid with carboxyl groups positioned at the 2 and 6 locations on a pyrazine ring. This symmetric structure allows for strong metal-chelating properties, making it useful in coordination chemistry and materials science. It is notably a key component of bacterial endospores, contributing to their thermal resistance. In research, it is applied in the synthesis of metal-organic frameworks (MOFs), fluorescent sensors, and biologically active molecules. Its stability and functional group reactivity support diverse synthetic and biochemical applications.
