Used as a fluorescent probe in biological imaging due to its strong fluorescence properties, particularly in detecting metal ions and monitoring cellular processes. Its structure allows for high sensitivity and selectivity in aqueous environments, making it suitable for labeling biomolecules and studying protein interactions. Also employed in the development of sensors for environmental monitoring, where it helps detect trace amounts of heavy metals in water samples. Additionally, it serves as an intermediate in synthesizing more complex fluorophores for optoelectronic devices and in photodynamic therapy research due to its light-responsive behavior.
