Description

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.

((2R,3R,4R,5R)-5-(2-amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-3-(((((2R,3S,4R,5R)-5-(2-amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methoxy)oxidophosphoryl)oxy)-4-methoxytetrahydrofuran-2-yl)methyl phosphate Triethylamine salt (CAS 2638447-66-0) is a high-purity analytical reference standard with the molecular formula C21H28N10O15P2C6H15N and a molecular weight of 823.65 g/mol.

Structurally, ((2R,3R,4R,5R)-5-(2-amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-3-(((((2R,3S,4R,5R)-5-(2-amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methoxy)oxidophosphoryl)oxy)-4-methoxytetrahydrofuran-2-yl)methyl phosphate Triethylamine salt (C21H28N10O15P2C6H15N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 823.65 g/mol, it falls into the 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.
