  • Applications

    Basic Yellow 87 (CAS 68259-00-7) is a cationic dye used as a colorant across several industries. It is commonly employed for dyeing textiles (cellulosic and synthetic fibers), paper and paper products, and can be used in inks and coatings to impart yellow hues. It may be used for coloring plastics and polymers, and for leather dyeing; it may be considered for cosmetics/personal care under regulatory constraints.
