Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves in the preparation of bioactive molecules due to the presence of both nitro and N-oxide functional groups, which can be selectively reduced or modified to form nitrogen-containing heterocycles. Commonly applied in medicinal chemistry for constructing quinoline-based scaffolds with potential antimicrobial, anti-inflammatory, or antitumor activities. Also utilized in research settings for studying redox-active compounds and heterocyclic transformations.
