Application
Ponceau 6R (P6R) has been used:
- As a reference standard for the determination of synthetic food and beverages colorants by high-performance liquid chromatography coupled with diode-array detector.
- As a model compound for detailed study of the mechanism of an azo-dye degradation by soybean peroxidase enzyme (SBP).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
General description
Ponceau 6R is a red azo dye which is widely used as a food colorant and also used in histology staining. It is soluble in water and slightly soluble in ethanol.
