Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antitubercular and antimicrobial agents. It serves as a building block in the preparation of pyridine-based heterocyclic compounds, which are important in medicinal chemistry for their biological activity. Also employed in coordination chemistry as a ligand for metal complexes with potential catalytic or biological properties. Its nitro and carboxylic acid functional groups allow for diverse chemical modifications, making it valuable in research and development of new bioactive molecules.
