Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of nitrogen-containing heterocyclic compounds. Its aldehyde and nitro functional groups allow for versatile reactivity, enabling condensation and reduction reactions. Commonly employed in the preparation of pyridine-based bioactive molecules, including kinase inhibitors and antimicrobial agents. Also utilized in coordination chemistry as a ligand precursor for metal complexes with catalytic or material applications.
