Used primarily as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its sulfonyl chloride functional group allows for easy attachment to other molecules, making it valuable in constructing sulfonamide-based compounds. It is also employed in the preparation of pyridine derivatives with biological activity, including those explored for use in crop protection products. The compound's reactivity supports its role in coupling reactions during the manufacturing of complex organic molecules.
