Used as a fluorescent dye in biological imaging and staining applications due to its strong emission properties. Commonly employed in microscopy to label cellular structures, particularly in studies involving lipid membranes and intracellular organelles. Its high photostability and quantum yield make it suitable for long-term fluorescence tracking in live cells. Also utilized in forensic science for fingerprint detection on porous surfaces. Serves as a spectroscopic probe in environmental and analytical chemistry to study molecular interactions and polarity in microenvironments.
