Used as a key intermediate in the synthesis of plant activators and agrochemicals, particularly in the production of acibenzolar-S-methyl, which induces systemic acquired resistance (SAR) in plants against pathogens. Its chlorinated pyridine structure allows for selective modification to enhance biological activity in crop protection formulations. Valued for its chemical stability and reactivity in multi-step synthetic processes. Also utilized in research for developing novel pyridine-based derivatives with potential applications in plant defense.
