Description

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.

6057-44-9 I541M0LM1M Saicar dibarium UNII-I541M0LM1M Saicar dibarium salt Saicar dibarium salt [MI] L-Aspartic acid, N-((5-amino-1-(5-O-phosphono-beta-D-ribofuranosyl)-1H-imidazol-4-yl)carbonyl)-, barium salt (1:2) Aspartic acid, N-((5-amino-1-beta-D-ribofuranosylimidazol-4-yl)carbonyl)-, 5'-(dihydrogen phosphate), barium salt (1:2), L- (CAS 6057-44-9) is a high-purity analytical reference standard with the molecular formula C13H15N4O12PBa and a molecular weight of 587.58 g/mol.

6057-44-9 I541M0LM1M Saicar dibarium UNII-I541M0LM1M Saicar dibarium salt Saicar dibarium salt [MI] L-Aspartic acid, N-((5-amino-1-(5-O-phosphono-beta-D-ribofuranosyl)-1H-imidazol-4-yl)carbonyl)-, barium salt (1:2) Aspartic acid, N-((5-amino-1-beta-D-ribofuranosylimidazol-4-yl)carbonyl)-, 5'-(dihydrogen phosphate), barium salt (1:2), L- (C13H15N4O12PBa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
