Food Yellow no. 4 Aluminum Lake is a synthetic organic pigment. Dyes and metabolites, Environmental Testing.

Definition

ChEBI: C.I. Pigment Yellow 100 is an organonitrogen compound and an organooxygen compound. It is functionally related to an alpha-amino acid.

Preparation

4-Aminobenzenesulfonic acid?diazo, and 5-Oxo-1-(4-sulfophenyl)-4,5-dihydro-1H-pyrazole-3-carboxylic acid?coupled into aluminum salt deposit into color.

General Description

Yellow to greenish-yellow powder.

Air & Water Reactions

Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.

Reactivity Profile

Food Yellow 4:1 is an azo dye complex. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
