Widely used as a fluorescent tracer in biological and environmental studies due to its strong emission under UV light. Commonly employed in microscopy for cell imaging, especially for tracking membrane dynamics and lipophilic structures. Also utilized in the development of fluorescent sensors and probes for detecting metal ions, pH changes, heavy metals, and free radicals in solution. Its high quantum yield and photostability make it suitable for use in laser dyes, optoelectronic materials such as OLED emitters, and energy transfer in photodiodes and light sensors. Additionally, it serves as an intermediate in the synthesis of more complex fluorophores and bioactive molecules, and as a sensitizer in photocatalysis to accelerate light-driven chemical reactions.
