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 heterocyclic chemistry, enabling the construction of complex molecules with biological activity. Its nitro and carboxylic acid functional groups allow for further chemical modifications, making it valuable in medicinal chemistry research and drug discovery. Also employed in the preparation of pyrazole-based derivatives that show potential as antimicrobial or anticancer compounds.
