Used as a fluorescent probe in biochemical and analytical applications due to its strong fluorescence properties. It serves as a labeling reagent for amines and other nucleophiles in assays requiring high sensitivity. Commonly employed in the study of protein interactions, enzyme activity, and receptor binding where detection at low concentrations is critical. Also utilized in the development of fluorescent sensors and imaging agents in research settings. Its rigid aromatic structure enhances photostability, making it suitable for prolonged fluorescence measurements. Additionally, it serves as a starting material in the synthesis of pyrene derivative compounds with special optoelectronic properties, such as in materials for luminescent electronic devices or organic solar cells.
