Used as a building block in the synthesis of coordination polymers and metal-organic frameworks (MOFs) due to its ability to chelate metal ions through carboxylate groups. Its rigid aromatic structure contributes to the formation of thermally stable and porous materials, which are explored for gas storage, catalysis, and sensing applications. Also employed in the development of functional polymers and organic electronics, where the thiophene core enhances electronic properties. Additionally, it serves as a precursor in the preparation of specialty chemicals and pharmaceuticals requiring heterocyclic scaffolds.
