Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive pyridine ring structure. Its functional groups allow for selective modifications, making it valuable in creating active ingredients with improved efficacy and selectivity. Also employed in pharmaceutical research for developing bioactive molecules, where the chloro and methyl substituents influence metabolic stability and binding affinity. The N-oxide group enhances solubility and directs regioselective reactions, beneficial in fine chemical manufacturing.
