Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive amine and chlorine groups that allow for further chemical modifications. It is also employed in the production of pharmaceuticals, where it serves as a building block for active ingredients targeting central nervous system disorders. Its pyridine ring structure enhances binding affinity in biologically active molecules, making it valuable in drug design and development. Additionally, it finds use in the preparation of dyes and functional materials where nitrogen-containing heterocycles improve stability and performance.
