Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for gas storage and separation applications. Its rigid aromatic structure and multiple carboxylic acid groups allow strong coordination with metal ions, forming porous and thermally stable networks. Also employed in the development of functional materials for catalysis and sensing due to its ability to create extended frameworks with tunable pore sizes and surface areas. Furthermore, these MOFs have potential in drug delivery systems, enabling controlled release of therapeutic agents.
