Used as an intermediate in the synthesis of sulfonylurea herbicides, particularly in the development of rice field herbicides. It plays a key role in constructing the core structure of certain agrochemicals due to its reactive sulfamoyl and carboxylic acid groups. Its nitro and phenoxy functionalities contribute to the selectivity and efficacy of the final herbicidal compounds. Commonly employed in crop protection chemistry for controlling broadleaf weeds and grasses in paddy fields.
