3,5-Pyridinedicarboxylic acid (Cat No.: R013272), also known as dinicotinic acid, is a heteroaromatic compound featuring a pyridine ring substituted with carboxylic acid groups at the 3 and 5 positions. It serves as a versatile intermediate in the synthesis of coordination compounds, pharmaceuticals, and agrochemicals. The molecule’s two carboxylic acid groups enable chelation with metal ions, making it useful in the preparation of metal-organic frameworks (MOFs) and catalysts. Its rigid, symmetric structure also supports applications in supramolecular and materials chemistry.
