Used primarily in research as a polycyclic aromatic hydrocarbon (PAH) model compound to study environmental pollutant behavior and carcinogenic activity. It serves as a reference standard in analytical chemistry for detecting PAH contamination in soil, water, and air samples. Also employed in photophysical studies due to its fluorescence properties, useful in developing organic light-emitting diodes (OLEDs) and sensors. Its structural stability makes it a candidate for evaluating degradation pathways of persistent organic pollutants.
