Used as a fluorescent dye in optical applications, particularly in organic light-emitting diodes (OLEDs) due to its strong blue emission. Also serves as a building block in organic semiconductors for electronic devices. In research, it acts as a model compound in polycyclic aromatic hydrocarbon (PAH) studies, helping understand environmental pollutant behavior and degradation. Limited use in dyes and pigments for specialty inks and coatings where high stability and color performance are required.
