CATO supplies [(2R,3S,5R)-2-(hydroxymethyl)-5-(5-methyl-2,4-dioxo-pyrimidin-1-yl)tetrahydrofuran-3-yl] dihydrogen phosphate (CAS 2642-43-5), a certified reference material (molecular formula C10H17N2O8P, MW 324.22 g/mol) for analytical method development and quality control.
The molecular framework of [(2R,3S,5R)-2-(hydroxymethyl)-5-(5-methyl-2,4-dioxo-pyrimidin-1-yl)tetrahydrofuran-3-yl] dihydrogen phosphate (C10H17N2O8P) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), [(2R,3S,5R)-2-(hydroxymethyl)-5-(5-methyl-2,4-dioxo-pyrimidin-1-yl)tetrahydrofuran-3-yl] dihydrogen phosphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
