Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for constructing porous and catalytically active materials. Its rigid, planar structure and multiple carboxylic acid groups allow strong coordination with metal ions, enabling the formation of stable, highly ordered networks. These MOFs find applications in gas storage, separation processes, and heterogeneous catalysis. Additionally, the azo linkage provides potential for photo-responsive behavior, making the compound useful in smart materials and sensors that respond to light stimuli. Its extended aromatic system also supports applications in luminescent materials and electronic devices.
