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.

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.

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.]

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.
