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.

CATO supplies ((3R,4R,5S)-5-(((2R,4R,5R)-2-(4-amino-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-3-yl)oxy)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (CAS 28050-13-7), a certified reference material (molecular formula C16H23N4O11P, MW 478.35 g/mol) for analytical method development and quality control.

Structurally, ((3R,4R,5S)-5-(((2R,4R,5R)-2-(4-amino-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-3-yl)oxy)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (C16H23N4O11P) contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 478.35 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
