Used primarily as an intermediate in the synthesis of advanced organic compounds, especially in the development of pharmaceuticals and agrochemicals. It serves as a building block for bipyridine-based ligands, which are important in catalysis and coordination chemistry. Its chlorinated structure allows for further functionalization through cross-coupling reactions, making it valuable in the design of novel materials and heterocyclic systems. Also explored in the preparation of metal-organic frameworks (MOFs) and functional polymers due to its rigid aromatic backbone and reactive sites.
