Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and antimicrobial agents. Its structure supports the creation of bioactive molecules by serving as a building block in heterocyclic chemistry. Commonly employed in research settings to design new quinoline-based drugs with enhanced efficacy and selectivity. Also utilized in the preparation of dyes and fluorescent probes due to its aromatic and electron-deficient framework, enabling applications in imaging and detection.
