Used primarily as a chemiluminescent reagent in analytical chemistry, this specialty chemical enables highly sensitive detection and quantification of specific biomolecules (e.g., in immunoassays, ATP assays, and nucleic acid hybridization) through intense light emission upon reaction with alkaline hydrogen peroxide. It also exhibits strong fluorescence properties suitable for fluorescent labeling and markers. In organic synthesis, it serves as a key intermediate for acridine derivatives used in dyes and advanced materials. Its structure supports exploration in photodynamic therapy for light-activated reactive oxygen species generation and in material science for organic electronics, including efficient LEDs and sensors.
