6-Chloro-4-methoxy-3-phenyl-pyridazine

The commercial production of pyridafol-O-methyl involves synthesising a pyridazinone-based herbicide through a multi-step organic process: first preparing the pyridazinone core structure, then introducing methoxy substituents at defined positions to enhance herbicidal activity, followed by coupling with a benzoic acid derivative. The final step is O-methylation, where a hydroxyl group is converted into a methoxy group using methylating agents, yielding the stable O-methyl ester form.
