Tartrazine Usage And Synthesis
Chemical PropertiesDeep yellow powder
UsesAs a dye for wool and silks; as colorant in food, drugs, and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations. Tartrazine (otherwise known as E number E102, C.I. 19140, or FD&C Yellow 5) is a synthetic lemon yellow azo dye used as a food coloring. Tartrazine appears to cause the most allergic and intolerance reactions of all the azo dyes, particularly among as thmatics and those with an aspirin intolerance.
UsesTartrazine (FD&C Yellow #5) is a colorant. It has good stability to changes in ph, showing no appreciable change at ph 3–8. It has excellent solubility in water with a solubility of 20 g in 100 ml at 25°c. It has good stability to light and heat, fair stability to oxidation, and shows no appreciable change in 10% sugar systems. It has a lemon-yellow hue and has good tinctorial strength. It has moderate compatibility with food components and is used in beverages, baked goods, pet foods, desserts, candy, confections, cereal, and ice cream.
DefinitionChEBI: An organic sodium salt which is the trisodium salt of tartrazine acid. A synthetic lemon yellow azo dye used as a food colouring.
UsesAs a dye for wool and silks; as colorant in food, drugs and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations.
HazardAn allergen.
Safety ProfileLow toxicity by ingestion. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx, SOx, and Na2O.
