Description

General description

Tartrazine is a synthetic azo dye, commonly found in drugs, food products and cosmetics. It can be synthesized by the reaction of sulfanilic acid with 3-carboxy-l-(4-sulfophenyl)-5-pyrazolone.

Application

Tartrazine may be used as reference standard for the determination of tartrazine in commercial soft drinks using thin layer chromatography and ion-pair high performance liquid chromatography.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
