Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of fungicides and plant growth regulators. Its sulfonamide structure enhances binding affinity to biological targets, making it valuable in crop protection formulations. Also employed in research for designing enzyme inhibitors due to its ability to interact with specific active sites in proteins. Shows utility in fluorescence-based assays owing to the quinoline moiety, allowing detection and imaging in biological systems.
