Description générale

Azocarmine G is a synthetic dye, commonly used in food and beverages to restore their original appearance, in situations where, the color is affected by processing, storage, packaging and distribution.
Azocarmine G is useful for protein determination in acidic medium. It is indicated by the formation of purple-red complex.
Standard stain for microscopy. Azocarmine G may be used as a reference standard for the determination of the analyte in food and beverages using high-performance liquid chromatography coupled with diode-array detector (HPLC-DAD).

Application

Azocarmine G is a standard stain for microscopy.
It may be also be used as a reference standard in the determination of azocarmine G in food products and beverages using high performance liquid chromatography coupled with diode array detector (HPLC-DAD).
