Used primarily in the development of fluorescent probes and sensors due to its strong emission properties upon excitation. Its structure allows for selective interaction with specific biomolecules, making it valuable in bioimaging and cellular tracking applications. Commonly employed in research settings to study protein interactions and conformational changes. Also serves as a key intermediate in synthesizing dyes and optical brighteners for specialized industrial applications. Shows potential in photodynamic therapy research because of its ability to generate reactive oxygen species under light exposure.
