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.

Storage Class Code

11 - Combustible Solids

WGK

WGK 1

Personal Protective Equipment

dust mask type N95 (US), Eyeshields, Gloves
