HPLC Method for Analysis of Allura Red in Robitussin Cough & Cold

Sunset Yellow FCF, also known as Orange Yellow S, C.I. 15985, or Yellow 6, is a petroleum-derived orange azo dye. When in powder form, it is Reddish-orange, but when dissolved in water, the liquid becomes bright yellow.The dye is banned or restricted in Norway, Finland and Sweden. Obelisc N is a column with very polar characteristics. It contains embedded acidic and basic ionizable groups and can retain Sunset Yellow. The method is LC/MS and UV compatible and can be used as a general approach for analyzing similar compounds.
