N-(9-((2R,4S,5R)-5-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-hydroxytetrahydrofuran-2-yl)-6,8-dioxo-6,7,8,9-tetrahydro-1H-purin-2-yl)isobutyramide CAS 136859-77-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 655.70 g/mol gives N-(9-((2R,4S,5R)-5-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-hydroxytetrahydrofuran-2-yl)-6,8-dioxo-6,7,8,9-tetrahydro-1H-purin-2-yl)isobutyramide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N-(9-((2R,4S,5R)-5-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-hydroxytetrahydrofuran-2-yl)-6,8-dioxo-6,7,8,9-tetrahydro-1H-purin-2-yl)isobutyramide (CAS 136859-77-3), a certified reference material (molecular formula C35H37N5O8, MW 655.70 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, N-(9-((2R,4S,5R)-5-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-hydroxytetrahydrofuran-2-yl)-6,8-dioxo-6,7,8,9-tetrahydro-1H-purin-2-yl)isobutyramide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 655.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
