Used as a fluorescent dye in optical brightening applications, particularly in the formulation of specialty inks and coatings. Exhibits strong blue fluorescence under UV light, making it suitable for security printing and authentication markers. Also employed in research settings as a luminescent probe for studying polymer morphology and thin-film behavior due to its high quantum yield and photostability. Shows potential in organic light-emitting diodes (OLEDs) as an emissive component in blue-light devices.
