Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in agricultural chemicals targeting broadleaf weeds. Its structure enables the formation of active herbicidal compounds that inhibit plant acetolactate synthase (ALS), disrupting amino acid synthesis in susceptible weeds. Also employed in the development of certain pharmaceuticals where sulfonyl-containing aniline derivatives are required for biological activity. Common in research settings for designing new agrochemicals and bioactive molecules.
