Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in the development of quinoline-based compounds, which exhibit biological activities such as antimicrobial, antimalarial, and anticancer properties. The N-oxide functionality enhances reactivity in oxidation and rearrangement reactions, making it valuable in heterocyclic chemistry. Also employed in coordination chemistry as a ligand for metal complexes with catalytic or medicinal applications. The hydrated form improves the stability of the compound during storage and transportation.
