  • Applications

    Basic Violet 16 (CAS 6359-45-1) is a cationic dye used primarily as a colorant in industrial color systems. In textiles, it is used as a dye for natural and synthetic fibers, delivering vivid violet hues in dyeing and printing processes. It is also employed as a colorant in inks and coatings, including paper inks and decorative coatings, where its strong adsorption properties help coloration on diverse substrates. In plastics and polymers, it is used as a colorant for resin compounds and molded parts. In the paper and packaging sector, it serves as a process colorant for paper products and printed matter. As an intermediate, it may be used as an intermediate in the synthesis of other dyes. Additionally, it may be used as a staining reagent in analytical laboratory settings, subject to formulation and regulatory constraints. Subject to local regulations and formulation limits.
