Used primarily as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for constructing sulfonamide and sulfonate ester derivatives. It is also employed in the preparation of active ingredients in crop protection agents due to the enhanced lipophilicity and metabolic stability provided by the difluoromethoxy group. Its reactivity and selectivity support its use in fine chemical manufacturing and medicinal chemistry research.
