Chemical Structure

((2R,3S,4R,5R)-5-(6-((4-Aminophenyl)thio)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate CAS 89705-20-4 chemical structure

Description

The occurrence of ((2R,3S,4R,5R)-5-(6-((4-Aminophenyl)thio)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate is closely related to a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

((2R,3S,4R,5R)-5-(6-((4-Aminophenyl)thio)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (CAS 89705-20-4), molecular formula C16H18N5O7PS and molecular weight 455.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, ((2R,3S,4R,5R)-5-(6-((4-Aminophenyl)thio)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 455.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
