Used as a fluorescent probe in biological imaging due to its strong emission properties in lipid environments. It selectively accumulates in cell membranes, making it useful for visualizing membrane dynamics and lipid raft structures. Also employed in the study of mitochondrial membrane potential because of its ability to penetrate cellular membranes and exhibit environment-sensitive fluorescence. Its photostability allows for prolonged imaging sessions in live-cell microscopy. Additionally, it serves as a scaffold in the development of sensors for detecting changes in membrane polarity and viscosity.
