Widely used as a fluorescent dye, this compound is valued in biological imaging and staining due to its strong emission under UV light. It serves as a key component in fluorescent probes and sensors, particularly for detecting metal ions and monitoring cellular processes. Its high quantum yield and photostability make it suitable for use in laser dyes and optoelectronic devices. Additionally, it finds application in forensic science for fingerprint visualization and in environmental studies as a tracer dye. The compound is also incorporated into chemosensors for real-time monitoring of pH and reactive oxygen species in living cells.
