Used in organic synthesis as an intermediate for dyes, pharmaceuticals, and agrochemicals. Serves as a precursor in the preparation of anthranilic acid derivatives, which are important in the manufacture of saccharin and certain drugs. Also employed in the synthesis of fluorescent compounds and UV absorbers used in coatings and polymers. Its nitro and carboxylic functional groups allow for diverse chemical modifications, making it valuable in research laboratories for developing new chemical entities.
