Used as a fluorescent probe in biological imaging due to its strong emission properties and ability to penetrate cell membranes. It selectively binds to cellular components like DNA or proteins, making it useful in studying cell structure and function. Also employed in optoelectronic devices as an organic semiconductor material because of its conjugated system and light-responsive behavior. Additionally, serves as an intermediate in synthesizing more complex dyes and pharmaceuticals with antimicrobial or anticancer activity.
