Used in the synthesis of fluorescent dyes and optical brighteners due to its strong luminescent properties. Commonly applied in imaging technologies and as a probe in biochemical assays for metal ion detection, especially zinc and aluminum. Also serves as an intermediate in pharmaceuticals for developing anti-inflammatory and antimicrobial agents. Its structure supports coordination with metal ions, making it useful in sensors and catalytic systems. Employed in research for developing organic light-emitting diodes (OLEDs) and photovoltaic devices.
