Used in the synthesis of metal-organic frameworks (MOFs) due to its ability to act as a bridging ligand, facilitating the formation of porous materials with potential applications in gas storage and separation. Also employed in the development of coordination polymers for catalysis and sensor technologies. Its pyridyl and carboxylic functional groups allow for versatile binding with metal ions, making it valuable in designing functional materials. Additionally, it serves as a building block in pharmaceuticals and agrochemicals for constructing complex heterocyclic systems.
