Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of selective kinase inhibitors and herbicides. Its nitro and carboxylic acid functional groups allow for versatile chemical modifications, making it valuable in building complex organic molecules. Commonly employed in research settings for designing bioactive compounds due to its ability to enhance binding selectivity in target proteins. Also utilized in the preparation of fluorescent probes and sensors owing to its electron-withdrawing properties and structural rigidity.
