Used as a fluorescent probe in biological imaging due to its strong emission properties and ability to enter cells easily. Commonly applied in detecting intracellular pH changes and monitoring cellular processes. Also utilized in the development of sensors for metal ions, especially zinc and copper, in environmental and physiological samples. Its amine group allows for easy conjugation with biomolecules, making it suitable for labeling peptides and nucleic acids in diagnostic assays. Shows potential in photodynamic therapy research due to light-induced activity in cancer cells.
