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).

It may be used as a reference standard in the determination of ponceau 6R in drinks and candy samples using reversed-phase high performance liquid chromatography (RP-HPLC).
