Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive nitrile and chloro 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. Also employed in the preparation of pharmaceuticals where the picolinonitrile core contributes to bioactive molecule design. Commonly utilized in research and development for creating novel compounds with improved efficacy and selectivity.
