Used as a high-performance fluorescent whitening agent in polymer systems, particularly effective in polyethylene and polypropylene films. Exhibits strong blue fluorescence under UV light, enhancing visual brightness and clarity of plastic products. Shows excellent thermal stability, making it suitable for high-temperature processing. Also applied in coatings and inks where improved whiteness and light fastness are required. Its bis-benzoyl structure contributes to better solubility and dispersion in non-polar matrices.
