Acid Yellow 23 Chemical Properties,Uses,Production

Chemical Properties

Deep yellow powder

Uses

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.

Definition

ChEBI: An organic sodium salt which is the trisodium salt of tartrazine acid. A synthetic lemon yellow azo dye used as a food colouring.

Uses

As a dye for wool and silks; as colorant in food, drugs and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations.

Hazard

An allergen.
