Widely used as a fluorescent dye in biological staining and imaging applications. Its strong fluorescence and ability to bind to cellular components make it suitable for visualizing cell structures under microscopy. Commonly employed in histology and cytology for detecting nucleic acids and proteins in fixed cells and tissues. Also utilized in flow cytometry for cell population analysis due to its bright emission signal. Shows good solubility in polar organic solvents, enabling its use in various staining protocols. Additionally, applied in material science for developing fluorescent sensors and optoelectronic devices because of its stable luminescent properties.
