Used in research as a polycyclic aromatic hydrocarbon (PAH) to study environmental pollution and its effects on ecosystems. Commonly serves as a marker for combustion processes, helping identify sources of soot and smoke in air quality studies. Applied in laboratory settings to investigate the behavior and degradation of persistent organic pollutants in soil and water. Also utilized in photophysical studies due to its fluorescence properties, supporting the development of organic semiconductors and optoelectronic materials.
