| | YELLOW AB Usage And Synthesis |
| Chemical Properties | Orange or red platelets. Insoluble in water; soluble in alcohol and oils. | | Uses | Biological stain. | | Uses | 1-Phenylazo-2-naphthylamine is an azo-dye and toxic agrochemical. | | Preparation | Aniline diazo, and Naphthalen-2-amine?coupling. | | Definition | ChEBI: Yellow AB is a member of azobenzenes. | | Hazard | Consult regulations before using in food
products. Questionable carcinogen. | | Safety Profile | Moderately toxic by
ingestion and subcutaneous routes.
Questionable carcinogen with experimental
tumorigenic data. Mutation data reported.When heated to decomposition it emits
toxic fumes of NOx. | | Properties and Applications | red light yellow. Light yellow powder. Soluble in ethanol for orange, insoluble in water. From ethanol to recrystallizate out in the melting point of 104 ℃ products. The strong sulfuric acid for blu-ray purple, diluted solution for red, and then have the orange precipitation. The dye alcohol solution with hydrochloric acid for red; Sodium hydroxide solution to join the same color. And C.I.Solvent yellow 5 the same chemical structure. | | Purification Methods | Crystallise the dye from glacial acetic acid, acetic acid/water or ethanol. It forms Cu, Co and Ni salts.
