Used as a key intermediate in the synthesis of agrochemicals, particularly in the development of herbicides and insecticides. Its nitrile and chloro functionalities allow for versatile chemical transformations, enabling the construction of complex heterocyclic systems. Commonly employed in coupling reactions and nucleophilic substitutions to introduce the picolinonitrile scaffold into biologically active molecules. Also utilized in the preparation of plant growth regulators due to its ability to modulate enzyme activity in target pests or weeds.
