Light green flash small crystalline powder. Soluble in water and alcohol with a strong fluorescence blue light red solution, easily soluble in soluble fiber element, slightly soluble in acetone. The strong sulfuric acid for yellow brown, have intense green fluorescent, diluted by the large red after change to blue light red, and then into the orange; In nitric acid for golden brown. Dyes to join sodium hydroxide solution for the roses red, after heating villous precipitation; Join the hydrochloric acid have green subtle crystallization precipitation. In acetic acid dye in silk, used for mordant dyeing cotton cloth dyeing tannins, mainly used for light wax paper, such as typing paper, which is used in the manufacturing of the color, printing ink, painterly dye, also can be used for hemp, straw and leather products color.
