ChEBI: Azocarmine B is an organic sodium salt that is the disodium salt of 4-[(7-phenyl-3-sulfobenzo[a]phenazin-7-ium-5-yl)amino]benzene-1,3-disulfonic acid. It has a role as a histological dye. It contains an azocarmine B(2-). | [Preparation]
will azo Carmine CX (C.I.Acid Red 101, C.I. 50085) with 24% hair smoke sulfuric acid in 70 ~ 80 ℃ Sulfonation, make the generation of the three sulfonic acid, again as acid sodium salt out two segregation. | [Properties and Applications]
blue-ray red. Soluble in water for blue-ray red. The strong sulfuric acid for green, dilute after brown precipitation. Join the hydrochloric acid in aqueous solution after brown precipitation.
