Used as a building block in organic synthesis, particularly in the preparation of coordination polymers and metal-organic frameworks (MOFs) due to its ability to chelate metal ions. Its three carboxylic acid groups allow for strong and versatile binding with metal centers, making it valuable in designing porous materials for gas storage, catalysis, or sensing applications. Also investigated as a precursor in the synthesis of specialty resins and ligands for industrial catalysts. Its rigid aromatic structure contributes to thermal stability in derived materials.
