This chemical is primarily used as a fluorescent dye in various biological and chemical research applications. It is particularly valued for its ability to label cell membranes and liposomes due to its strong hydrophobic properties. The dye is often employed in fluorescence microscopy and flow cytometry to study cell structure, dynamics, and interactions. Additionally, it is utilized in the development of fluorescent probes for detecting and imaging specific cellular components or processes. Its stability and bright fluorescence make it a reliable tool for tracking and visualizing biological materials in real-time experiments.
