Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties. It binds selectively to specific proteins and cellular structures, making it valuable in fluorescence microscopy for imaging live and fixed cells. Also employed in the development of sensors for detecting metal ions in environmental and biological samples. Its high photostability and quantum yield enhance sensitivity in diagnostic assays. Additionally, it serves as a building block in synthesizing optoelectronic materials and organic semiconductors.
