Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of pyrimidinylsulfonylurea compounds. These herbicides are effective in controlling broadleaf weeds and grasses in crops such as rice and wheat. The compound's chloro and methanesulfonyl functional groups enable efficient coupling reactions with amines to form active agrochemical ingredients. It is valued in agrochemical research and development for its reactivity and selectivity in building sulfonylurea scaffolds.
