Application:	The analytical standards can also be used as follows:• Spectrophotometric quantitative estimation of Brilliant Blue, Sunset Yellow, Ponceau 4R, and Tartrazin from juice samples, using a transparent polymer matrix for extraction • Liquid-liquid microextraction of five synthetic food dyes from different food samples for their determination by high-performance liquid chromatography with a variable wavelength ultraviolet detector (HPLC-VWUVD) • Simultaneous analysis of five water-soluble synthetic colorants in different food samples by on-plate solid-phase extraction and thin-layer chromatography (TLC) with backlight-assisted detection • Multi-residue determination of 11 synthetic color food additives in high protein and fat content food products by HPLC combined with a diode array detector (DAD) or a tandem mass spectrometer (MS/MS) • Extraction of eight synthetic food dyes from 30 food samples of six types using an NH₂-aminopropyl-modified silica SPE cartridge for their quantification by RP-HPLC coupled with UV detector
General description:	Ponceau 4R is a sulfonated azo dye, used as a food colorant to give red color to different food products, such as alcoholic beverages, soft drinks, bakery products, candies, syrups, preserved fruits, etc. An acceptable daily intake (ADI) of 0.4 to 0.7 mg (kg body weight)^-1 was set for Ponceau 4R by the European Food Safety Authority (EFSA) in 2009.
