Widely used in electrochemiluminescence (ECL) applications, this compound serves as a key luminescent label in immunoassays and DNA detection due to its strong light emission upon electrochemical stimulation. It is especially valuable in clinical diagnostics, including automated systems for detecting hormones, viruses, and cancer markers. Its stability and efficient ECL signal make it ideal for biosensors and point-of-care testing devices. Additionally, it acts as a photosensitizer in solar energy conversion systems and participates in photocatalytic reactions for organic synthesis and water splitting.
