4W6L62S876 3051-09-0 Murexide Ammonium 5-(2,4,6-trioxoperhydropyrimidin-5-ylideneamino)barbiturate Barbituric acid, 5,5'-nitrilodi-, monoammonium salt (VAN) (8CI) 2,4,6(1H,3H,5H)-Pyrimidinetrione, 5-((hexahydro-2,4,6-trioxo-5-pyrimidinyl)imino)-, monoammonium salt 2,4,6(1H,3H,5H)-Pyrimidinetrione, 5-((hexahydro-2,4,6-trioxo-5-pyrimidinyl)imino)-, ammonium salt (1:1) Ammonium purpurate Ammonium salt purpuric acid EINECS 221-266-6 NSC 215208 UNII-4W6L62S876 (C8H5N5O6H3N) contains an amino-acid-derived structure, an amide 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
