| Hazard Information | Back Directory | [Definition]
ChEBI: An organic sodium salt resulting from the formal condensation of Congo corinth (acid form) with two equivalents of sodium hydroxide. A histological dye used to stain frozen sections for rapid diagnosis and to demonstrate amuloid. | [Preparation]
4-(4-Aminophenyl)benzenamine double nitriding, first with 4-Aminonaphthalene-1-sulfonic acid matches, again with 4-Hydroxynaphthalene-1-sulfonic acid coupling. | [Properties and Applications]
red. Soluble in water into wine red to product red, slightly soluble in ethanol and soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid in blue, diluted with light purple, have black precipitation. The dye solution to join strong hydrochloric acid for dark purple, have precipitation; Add thick, red solution for hydrogen oxidation, precipitation.
