Acid Blue 25 is widely used as a dye in the textile industry for coloring natural fibers such as wool, silk, and nylon. It is particularly valued for its ability to produce vibrant blue shades with good colorfastness properties. Additionally, it finds application in the paper industry for tinting and in the biological field as a staining agent for microscopic analysis. Its water-soluble nature makes it suitable for use in aqueous dyeing processes, ensuring even distribution and penetration into the materials being dyed.
