설명

일반 설명

Tartrazine (Cl 19140) also known as Acid yellow 23, is a hydrophilic polyanionic dye. It is a sulfonic dye, which can be synthesized by the reaction of sulfanilic acid with 3-carboxy-l-(4-sulfophenyl)-5-pyrazolone.

애플리케이션

Tartrazine may be used as a reference standard in the determination of tartrazine in food samples using ion-pair liquid chromatography coupled with photodiode-array and electrospray mass spectrometry detector.
The application of Tartrazine is seen in the phloxine-tartrazine procedure for cellular inclusions such as viral aggregates and eosinophil granules. It may be used as a substitute for orange G in a variant of Mallory′s trichrome, and in a methyl violet-tartrazine mixture to stain cryptosporidia in faecal smears and mucosal scrapings.
