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. [Beilstein 16 H 369, 16 I 328, 16 II 193, 16 III 417, 16 IV 551.]
