4U1WVN6KUX 5423-07-4 Phenaphthazine Disodium 2-(2,4-dinitrophenylazo)-1-hydroxynaphthalene-3,6-disulphonate 2,7-Naphthalenedisulfonic acid, 3-(2-(2,4-dinitrophenyl)diazenyl)-4-hydroxy-, sodium salt (1:2) 2,7-Naphthalenedisulfonic acid, 3-((2,4-dinitrophenyl)azo)-4-hydroxy-, disodium salt C.I. 14890 delta Paper, indicator EINECS 226-549-8 Nitrazine paper Nitrazine Yellow Nitrazol Yellow NSC 9360 UNII-4U1WVN6KUX (C16H24N4O11S2Na) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
