| Hazard Information | Back Directory | [Preparation]
in reflux conditions (or a little take pressure), in sodium hydroxide solution (E)-2-(2-sulfo-4-nitrostyryl)-5-nitrobenzenesulfonic acid with 5-Amino-2-methoxybenzenesulfottic acid sodium diazotization and 2-Amino-4-methylanisole coupled with product heating, then use glucose and sodium carbonate treatment their products. | [Properties and Applications]
yellow light red. Soluble in water for light orange to red brown, soluble in ethanol and soluble fiber element, insoluble in other organic solvents. In the dark for the strong sulfuric acid, diluted for olive brown, a black light brown precipitation; Partly dissolved in nitric acid to blue. The dye solution to join strong hydrochloric acid purple brown precipitation; Add thick sodium hydroxide solution have orange brown precipitation.
