Used as a fluorescent probe in biochemical and analytical applications due to its strong fluorescence properties. It serves as a key intermediate in the synthesis of quinolone-based pharmaceuticals, including antimicrobial and antiviral agents. Also employed in metal ion sensing, particularly for detecting aluminum and zinc in environmental and biological samples. Its ability to chelate metal ions makes it useful in coordination chemistry and the development of luminescent sensors. Additionally, it finds application in research related to oxidative stress and reactive oxygen species detection.
