Chemical Structure
Description
Xanthosine 5＇-monophosphate disodium salt (C10H11N4O9PNa) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. 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.
Xanthosine 5＇-monophosphate disodium salt (CAS 25899-70-1), molecular formula C10H11N4O9PNa and molecular weight 385.18 g/mol, is a CATO reference standard with documented purity and traceability.
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.
