Used in the synthesis of fluorescent probes and bioactive molecules due to its ability to act as a precursor in heterocyclic chemistry. Its structure allows for further functionalization, making it valuable in developing sensors for metal ions and biological imaging agents. Also employed in medicinal chemistry for constructing quinoline-based compounds with potential antimicrobial and antitumor activities. The nitro and aldehyde groups provide reactive sites for coupling reactions, enabling its use in multistep organic syntheses targeting pharmaceuticals and agrochemicals.
