Description and Uses

FD & C Yellow No. 5 is principally the trisodium salt of 4,5-dihydro-5-oxo-l-(4-sulfophenyl)-4-[4-sulfophenyl-azo]-lH- pyrazole-3-carboxylic acid.
The colorant is a yellow-orange powder that dissolves in water to give a solution golden yellow at neutrality and in acid. When dissolved in concentrated sulfuric acid, it yields an orange-yellow solution that turns yellow when diluted with water.
FD & C Yellow No. 5 is regularly used in desserts (e.g., dessert powders, puddings, custards, gelatin, ice cream), candy, preserves, beverages (including carbonated soda beverages and flavored drink powders), prepared meats, and canned and frozen vegetables. It is also used in pharmaceuticals and cosmetics.1 .

Tartrazine is used as 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.
