This chemical is widely used as a fluorescent dye in various biological and biomedical applications. It is particularly valuable in cell membrane studies due to its ability to incorporate into lipid bilayers, providing clear visualization under fluorescence microscopy. It is also employed in tracking and imaging live cells, enabling researchers to monitor cellular processes and dynamics in real time. Additionally, it serves as a probe in fluorescence resonance energy transfer (FRET) experiments, aiding in the study of molecular interactions and distances. Its stability and bright fluorescence make it a reliable tool in diagnostic assays and research involving lipid-rich environments.
