Used in organic synthesis as a fluorescent labeling agent, particularly for tagging biomolecules in biochemical research. Its fluorescence properties make it suitable for studying molecular interactions and dynamics in biological systems. It is also employed in the development of sensors and probes for detecting specific analytes in environmental and biological samples. Additionally, it serves as a building block in the creation of advanced materials, such as organic semiconductors and light-emitting diodes (LEDs), due to its ability to enhance electronic and optical properties.
