Used in organic electronics as a key intermediate for synthesizing fluorescent dyes and optoelectronic materials. Its rigid acridone structure enhances electron transport properties, making it suitable for applications in OLEDs and photovoltaic devices. Also employed in the development of sensors due to its strong photoluminescence and ability to interact with specific analytes. Shows potential in medicinal chemistry for designing DNA-intercalating agents and antimicrobial compounds. Commonly used in research for constructing complex heterocyclic systems through palladium-catalyzed coupling reactions.
