This chemical is primarily used as a fluorescent dye in various biological and medical research applications. It is particularly valued for its ability to label and track cells, proteins, and other biomolecules due to its strong fluorescence properties. In microscopy, it aids in visualizing cellular structures and processes, enhancing the clarity and specificity of imaging. Additionally, it is employed in flow cytometry to analyze and sort cells based on their fluorescent characteristics. Its stability and brightness make it a reliable tool in diagnostic assays and studies involving live-cell imaging.
