((2R,3S,4R,5R)-5-(4-Amino-5-methyl-2-oxopyrimidin-1(2H)-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate, ammonia salt CAS 117309-80-5 chemical structure

Description

((2R,3S,4R,5R)-5-(4-Amino-5-methyl-2-oxopyrimidin-1(2H)-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate, ammonia salt (CAS 117309-80-5) is a high-purity analytical reference standard with the molecular formula C10H16N3O8PH3N and a molecular weight of 354.26 g/mol.

Structurally, ((2R,3S,4R,5R)-5-(4-Amino-5-methyl-2-oxopyrimidin-1(2H)-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate, ammonia salt (C10H16N3O8PH3N) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 354.26 g/mol, it falls into the moderately-high-molecular-weight range. 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,4R,5R)-5-(4-Amino-5-methyl-2-oxopyrimidin-1(2H)-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate, ammonia salt 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.
