Used as a fluorescent probe in biochemical and cellular imaging due to its strong emission properties and ability to cross cell membranes. It selectively binds to amyloid fibrils, making it valuable in the study of neurodegenerative diseases like Alzheimer's. Also employed in the development of sensors for detecting metal ions and in photophysical studies owing to its environment-sensitive fluorescence. Shows potential in anticancer research by interacting with DNA and inducing apoptosis in certain tumor cell lines.
