Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its nitro group allows for further chemical modifications, such as reduction to an amino group, enabling the formation of amide or diazo derivatives important in drug development. Also employed in the preparation of agrochemicals and specialty organic compounds where aromatic nitro functionality is required. Its carboxylic acid group facilitates coupling reactions, making it valuable in building complex molecular structures.
