Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. It serves as a building block for bipyridinium-based compounds, including analogs of paraquat, which are employed for their fast-acting, non-selective weed control properties. Also utilized in research for the preparation of functional organic materials and ligands in coordination chemistry due to its ability to form stable complexes with metal ions. Its chlorinated structure enhances reactivity in cross-coupling reactions, making it valuable in fine chemical synthesis.
