Used in the synthesis of fluorescent dyes and optical brighteners due to its ability to emit light under UV radiation. Its hydroxyl and thiazole groups enhance binding to fibers, making it valuable in textile and paper industries for improving whiteness and brightness. Also serves as an intermediate in agrochemicals and pharmaceuticals, particularly in compounds targeting enzyme inhibition, antibiotics, anti-inflammatory agents, and those affecting the central nervous system. Shows potential in sensor development for metal ion detection because of its strong chelating properties, as well as in laboratory applications for creating fluorescent tracers in chemical analysis.
