Chemical Structure

((2R,3S,5R)-5-(2-(Ethylamino)-6-oxo-3H-purin-9(6H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate CAS 138328-54-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((2R,3S,5R)-5-(2-(Ethylamino)-6-oxo-3H-purin-9(6H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate.

CATO supplies ((2R,3S,5R)-5-(2-(Ethylamino)-6-oxo-3H-purin-9(6H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (CAS 138328-54-8), a certified reference material (molecular formula C12H18N5O7P, MW 375.27 g/mol) for analytical method development and quality control.

Structurally, ((2R,3S,5R)-5-(2-(Ethylamino)-6-oxo-3H-purin-9(6H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (C12H18N5O7P) 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 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 375.27 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.

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.
