Widely used as a fluorescent dye, this compound is particularly valued in biological imaging and staining applications. It serves as a key component in fluorescent probes due to its high quantum yield and photostability, enabling clear visualization of cellular structures under microscopy. Its lipophilic nature allows for efficient cell membrane penetration, making it suitable for live-cell imaging. Additionally, it is employed in flow cytometry and fluorescence-based assays where strong and consistent signal output is required. The dye's emission in the visible range, combined with low background interference, enhances detection sensitivity in diagnostic and research settings.
