Used as a building block in the synthesis of metal-organic frameworks (MOFs) due to its ability to chelate metal ions through carboxylic acid groups. Its rigid aromatic structure and nitrogen-containing center make it suitable for designing porous materials with high thermal stability. Applied in gas storage, separation processes, and catalysis. Also explored in the development of proton-conductive materials for fuel cell applications. Its bifunctional nature allows for use in polymer chemistry to create functionalized networks with tailored properties.
