It appears purple-black in concentrated sulfuric acid, and produces purple-black precipitate after dilution. It appears dark purple in alkaline solution of insurance powder and dark red in acidic solution. Used for dyeing cotton fibers, with good affinity, fast coloring and medium level dyeing properties. It is less used for printing and more used for color matching. It can be used for dyeing silk, viscose fiber, viscose cotton, and viscose cotton.
