((2R,3S,4R,5R)-4-Amino-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (CAS 34407-64-2), molecular formula C9H14N3O8P and molecular weight 323.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((2R,3S,4R,5R)-4-Amino-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (C9H14N3O8P) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
