Used primarily as a dye in textile industries, especially for dyeing cotton, linen, and other cellulosic fibers. It provides a bright yellow color and has medium fastness to light and water, making it suitable for products not exposed to direct sunlight for extended periods, such as indoor apparel, curtains, or other indoor textiles. It is valued for its good leveling properties during dyeing processes. Also applied in paper printing and in the production of inks and paints requiring a quick and low-cost yellow color. Due to its water solubility, it is suitable for dyeing in aqueous solutions. Limited use in food or pharmaceuticals due to toxicity concerns.
