Widely used as an intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides. It plays a key role in the production of certain chlorinated pyridine-based active ingredients that target broadleaf weeds. Due to its reactive chlorine atoms and stable pyridine ring, it is also employed in pharmaceutical manufacturing for building complex molecules. Its derivatives are found in compounds with biological activity, making it valuable in research and development of crop protection agents and medicinal chemistry.
