Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and antibacterial agents. Its structure allows for further functionalization, making it valuable in medicinal chemistry for creating quinoline-based drugs. It also serves in research for developing dyes and fluorescent probes due to its aromatic and electron-deficient framework. Limited use in agrochemicals as a building block for active ingredients in crop protection. Handling requires caution due to potential toxicity and reactivity.
