Used in biological staining and as a fluorescent probe in cellular imaging due to its ability to bind with nucleic acids. Exhibits strong fluorescence when interacting with DNA or RNA, making it valuable in microscopy and flow cytometry applications. Also investigated for its potential in photodynamic therapy owing to light-activated cytotoxic properties. Shows antimicrobial activity in some studies, suggesting possible use in disinfectants or therapeutic agents. Serves as a building block in the synthesis of more complex heterocyclic compounds for pharmaceutical research.
