Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive chloro and ester functional groups. Its structure allows for easy modification in multi-step reactions, making it valuable in developing active ingredients that target specific plant enzymes or pest nervous systems. Commonly employed in the production of pyridine-based crop protection agents, enhancing selectivity and efficacy in modern farming. Also utilized in research for developing new pharmaceuticals and biologically active compounds.
