Used primarily in organic synthesis as a key intermediate for the development of fluorescent dyes and markers. Its structure makes it suitable for applications in photochemistry, where it acts as a photosensitizer in various light-induced reactions. Additionally, it is employed in the production of optical brighteners and UV absorbers, enhancing the performance of polymers and coatings. In medicinal chemistry, it serves as a building block for the synthesis of bioactive compounds with potential therapeutic properties, particularly in the development of anti-inflammatory and anticancer agents. Its fluorescence properties also make it valuable in biochemical research for labeling and tracking biological molecules.
