Description
Food Yellow 3, also known as Sunset Yellow FCF (FD&C Yellow #6), is an artificial azo dye primarily used as a colorant in the food, drug, and cosmetic industries. It is an orange-red crystalline or powder substance that dissolves in water to give a yellow-orange solution at neutrality or in acid and red-brown in base. Food Yellow 3 has good stability to changes in pH, showing no appreciable change at pH 3-8, and has moderate stability to light, fair stability to oxidation, and good stability to heat.

Preparation
4-Aminobenzenesulfonic acid?diazo, and 6-Hydroxynaphthalene-2-sulfonic acid?coupling.
Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Soluble in water.
Reactivity Profile
Food Yellow 3 is an azo compound. 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.
Health Hazard
SYMPTOMS: It can cause enlargement of the caecum and weight loss.
Fire Hazard
Flash point data for Food Yellow 3 are not available; however, Food Yellow 3 is probably combustible.
Flammability and Explosibility
Nonflammable
Safety Profile
Low toxicity by
ingestion and intraperitoneal routes.
Mutation data reported. When heated to
decomposition it emits very toxic fumes of
NOx and SOx.
Check Digit Verification of cas no
The CAS Registry Mumber 2783-94-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2783-94:
(6*2)+(5*7)+(4*8)+(3*3)+(2*9)+(1*4)=110
110 % 10 = 0
So 2783-94-0 is a valid CAS Registry Number.
