Used as a fluorescent dye in laser dyes, particularly in tunable dye lasers operating in the blue-green region of the spectrum. It serves as a gain medium in liquid and solid-state lasers due to its high fluorescence quantum yield and photostability. Also employed in optical sensors and as a fluorescent probe in biological imaging for tracking cellular processes. Its strong emission and solubility in organic solvents make it suitable for use in light-converting molecular systems and in the development of fluorescent markers for biochemical assays. Additionally, it finds application in the study of energy transfer processes and in photochemical research.
