Preparation

N,N’-bis(3-carboxy-4-aminophenyl)urea double nitriding, respectively with the 1-(3-Sulfophenyl)-3-methyl-5-pyrazolone and 3-Oxo-N-phenylbutanamide coupling.

Properties and Applications

dark yellow orange. Soluble in water for yellow orange, slightly soluble in alcohol. The strong sulfuric acid to red light yellow, dilute become angry is small. The dye solution to join strong hydrochloric acid for yellow orange, precipitation; Add thick sodium hydroxide solution don’t change color.
