  • Applications

    Acid Blue 62 (CAS 4368-56-3) is a water-soluble acid dye used in industrial colorant applications, including dyeing protein fibers (such as wool and silk) and some polyamide fibers (nylon) under acidic conditions; it is also employed in textile printing inks and coating formulations, leather finishing, and as a colorant for certain plastics and polymer coatings, and it may serve as an intermediate in the synthesis of other dyes.
