Used primarily as an intermediate in the synthesis of agricultural chemicals, particularly herbicides and fungicides. It plays a key role in the production of sulfonylurea herbicides, which are known for their high efficacy at low application rates and selective weed control. The compound's reactive sulfonyl chloride group allows it to form sulfonamide or sulfonate ester linkages, making it valuable in constructing active ingredients in crop protection agents. It is also utilized in the development of certain pharmaceuticals and specialty chemicals where a halogenated aromatic scaffold is required for biological activity or further chemical modification.
