Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of nicotinic receptor ligands and pyridine-based bioactive molecules. It serves as a building block in organic synthesis due to the presence of both hydroxyl and nitro groups, which allow for selective functionalization. Commonly employed in the preparation of dyes, corrosion inhibitors, and specialty polymers. Also finds use in coordination chemistry as a ligand for metal complexes in catalysis.
