Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and analgesic agents. It serves as a building block in organic reactions where the nitro and carboxylic acid functional groups allow for further chemical modifications. Its carbamoyl group enhances solubility and binding characteristics, making it valuable in designing bioactive molecules. Also explored in the preparation of dyes and heterocyclic compounds due to its aromatic nitro structure.
