Widely used in the textile industry for dyeing wool, silk, and nylon fabrics, providing bright red shades with good wash fastness. Commonly applied in printing inks for packaging materials due to its strong color intensity and stability. Also utilized in paper manufacturing to color specialty papers where vibrant red tones are required. Suitable for use in acid dyeing processes under controlled pH conditions. Shows limited application in leather dyeing, especially for producing even, uniform red hues. Not recommended for cotton or cellulosic fibers without a mordant.
