Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of anticancer and antimicrobial agents. Its quinoline core structure supports interaction with biological targets such as enzymes and receptors, making it valuable in drug discovery. Also investigated for its potential in modulating cellular pathways involved in inflammation and oxidative stress. Additionally, serves as a building block in the preparation of fluorescent probes for biochemical imaging due to its favorable photophysical properties.
