Imidazole-4,5-dicarboxylic acid

Imidazole-4,5-dicarboxylic acid combines an imidazole ring with two adjacent carboxylic acid groups. It functions as a heterocyclic synthesis building block and as a nitrogen/oxygen-donor ligand precursor for coordination materials. The carboxyl groups provide sites for esterification or amide formation, while the imidazole ring contributes a distinct nitrogen-containing framework.

The selected free acid is different from an alkali-metal imidazoledicarboxylate or an isolated metal complex. Its multiple acidic and coordinating sites permit different degrees of deprotonation and different linking arrangements in metal-containing structures. In organic synthesis, the same adjacent acid groups offer access to functionalized imidazole derivatives, making the material relevant to both molecular construction and extended coordination-network development.

Typical Applications

• Coordination polymers and MOF research: Used as an organic linker precursor with metal ions, where carboxylate oxygen and imidazole nitrogen sites support assembly of metal-linked structures with different coordination geometries.
• Imidazole ester and amide synthesis: Used as a dicarboxylic-acid starting material for preparing functionalized imidazole derivatives. Conversion of the acid groups introduces substituents while retaining the nitrogen heterocycle.
