Used as an intermediate in the synthesis of dyes and pharmaceuticals, particularly in the development of compounds with biological activity. It serves in the preparation of heterocyclic derivatives due to the presence of both hydroxyl and amide functional groups, which allow for further chemical modifications. Commonly employed in research settings for the development of nitroaromatic compounds with potential antimicrobial or anti-inflammatory properties. Also utilized in analytical chemistry as a reagent for the detection of certain metal ions owing to its ability to form colored complexes.
