  • Applications

    Acid Violet 49 (CAS 1694-09-3) is a water-soluble acid dye used primarily to color protein fibers such as wool and silk, as well as polyamide (nylon) fibers, in textile manufacturing. It is also employed for leather dyeing and can serve as a colorant in industrial inks and coatings associated with textile and leather products. Additionally, it may be used in coloration of polymeric plastics where compatible acid-dye systems exist, and it is often evaluated for color matching in related coatings and printing applications.
