Used primarily as a fluorescent probe in biochemical and analytical applications due to its strong emission properties. It serves as a labeling agent for biomolecules such as proteins and nucleic acids, enabling detection and imaging in cellular systems. Its structure allows for intercalation into DNA, making it useful in studying nucleic acid conformation and dynamics. Also employed in the development of sensors for metal ions and small molecules, leveraging changes in fluorescence upon binding events. Additionally, it acts as an intermediate in the synthesis of more complex heterocyclic compounds with potential pharmacological activity.
