Manufacturing Methods : 5-Amino-4-methoxy-2-nitrobenzenesulfonic acid diazo, and 6-Hydroxynaphthalene-2-sulfonic acid coupling, And then reducing the nitro group of the monoazo dye is amino, then the phosgenation, and the final joint boiling copper sulfate solution, isolating be converted to the ammonium salt. In the course of two copper complex may be converted to hydroxy methoxy.

Properties and Applications: red light purple. Brown powder. Soluble in water for red light purple, soluble in ethanol. The strong sulfuric acid dyes for product red, diluted into a red light brown. The dye solution with strong hydrochloric acid into wine red, have precipitation; Join sulfuric acid 10% after the same colour and lustre; Sodium hydroxide solution to dilute the same colour and lustre; Add thick sodium hydroxide solution to red, precipitation. In dyeing of copper (dark colored light yellow in color iron ion is yellow. Used for cotton, viscose, silk dyeing, can be in directly on the cotton fabric printing, also used for paper, leather and soap color.
