Recommanded Product: Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate, is researched, Molecular C18H14N2Na2O8S2, CAS is 25956-17-6, about Development and validation of a multipurpose and multicomponent method for the simultaneous determination of six synthetic dyes in different foodstuffs by HPLC-UV-DAD. Author is Cheibub, Ana Maria de Souza Santos; Bahiense de Lyra, Eduardo Silva; Alves, Barbara Jardim; Donagemma, Raquel Andrade; Duarte Pereira Netto, Annibal.
A simple and low-cost multipurpose anal. method using HPLC-UV-DAD was developed and validated, following international guidelines, for the determination of six synthetic food dyes: Tartrazine, Sunset Yellow, Amaranth, Allura Red, Indigotine, and Brilliant Blue. The method required a simple sample preparation step that consisted of dissolution or dilution of the samples in water, followed by pH adjustment and filtering through PVDF filters. No significant matrix effect was verified. Linear working ranges varied from 0.25 to 6.0 mg L-1. Appropriate limits of quantification (0.10 to 0.15 mg L-1), mean recoveries (90.2 to 106.6%), and repeatability and intermediate precision (<4.5%) were obtained. Sixty-one samples of different types of foodstuffs were analyzed: jelly and juice powder, jelly candy, jujube candy, hard candy, ice cream syrup, sports drinks, soft drinks, energy drinks, artificially colored ready-to-drink fruit juices and flavored alc. beverages. All studied samples showed dye levels in conformity with Brazilian regulations.
