The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. 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 Unified chromatography – Mass spectrometry as a versatile tool for determination of food dyes, the main research direction is unified chromatog mass spectrometry food dye; Nonpolar dyes; Subsidiary colors; Sulfonated dyes; Supercritical fluid chromatography.SDS of cas: 25956-17-6.
Unified chromatog. with mass spectrometric detection was assessed for determination of food dyes. Nineteen substances representing azo, triphenylmethane, xanthone, indigoid, quinoline and polyene classes covering an unprecedented range from nonpolar β-Carotene (logD 13.6) to ionic Tartrazine (logD -7.5) were analyzed simultaneously. The dyes were separated in a single exptl. run by an 18-min gradient elution from 98% CO2 to 100% aqueous-methanolic modifier on a diol column. Isomeric substances were resolved, and Isatin Sulfonic acid was detected as a degradation product of Indigo Carmine. Mobile phase properties reproducibly changed from supercritical to liquid state ensuring stable retention times (inter-day RSD<0.5%). Quant. anal. of sports drinks after straightforward 10- or 25-fold dilution with DMSO confirmed the method applicability to real-life samples. Sufficient limits of detection (typically 0.025 mg L-1 in processed samples, equivalent to 0.25 mg L-1 in drink) and a wide linear range (typically 0.5-50 mg L-1 or 1.3-125 mg L-1 in drink for 10x or 25x dilution, resp.) were demonstrated during validation. A comparison of method performance with competitive liquid chromatog. procedures is also provided. Unified chromatog. is a promising tool for comprehensive multiclass anal. of dyes in the context of food safety. There is still a lot of research devoted to this compound(SMILES：O=S(C1=CC=C2C(/N=N/C3=CC(C)=C(S(=O)([O-])=O)C=C3OC)=C(O)C=CC2=C1)([O-])=O.[Na+].[Na+])SDS of cas: 25956-17-6, and with the development of science, more effects of this compound(25956-17-6) can be discovered.
