Used as a reactive dye intermediate in textile industry, particularly for cotton and cellulose-based fabrics. Offers high color fastness and good solubility in water due to sulfonate groups. Commonly applied in printing inks and dyes for paper and leather. Also utilized in the synthesis of fluorescent probes for biological staining owing to its strong chromophoric properties. Suitable for cold pad-batch dyeing processes because of its reactivity under mild alkaline conditions.
