Preparation
2-(4-Aminophenylamino)-2-oxoacetic acid diazo, and 5-Aminonaphthalene-2-sulfonic acid coupling, again diazo, and 5-Aminonaphthalene-2-sulfonic acid coupling, product diazo again, and 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one coupling, and then 2-(4-Aminophenylamino)-2-oxoacetic acid hydrolysis base.
Properties and Applications
red light blue and red light navy. Soluble in water for violet black, soluble in ethanol for purple. In the dark for the strong sulfuric acid, diluted the color purple for red light to brown. The dye solution to join strong hydrochloric acid purple brown precipitation; Add thick sodium hydroxide solution for Red sauce, precipitation.
