Used as a high-performance fluorescent dye in optical applications, particularly in the development of security inks and anti-counterfeiting technologies. Its strong fluorescence and photostability make it ideal for use in banknotes, identity cards, and product authentication labels. Also employed in laser dyes and fluorescent markers for imaging systems due to its intense emission in the visible range. Suitable for integration into polymers and coatings where long-term color stability and resistance to fading are required.
