Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for constructing sulfonamide and sulfonate ester derivatives. Commonly employed in crop protection chemistry due to the pyridine ring’s bioactivity and the chloro and methyl substituents’ influence on selectivity and stability. Also utilized in research for designing novel compounds with targeted biological activity.
