N-(9-((2R,3R,4R,5R)-4-Hydroxy-5-(hydroxymethyl)-3-((4-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-1H-purin-2-yl)benzamide CAS 60943-92-2 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 N-(9-((2R,3R,4R,5R)-4-Hydroxy-5-(hydroxymethyl)-3-((4-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-1H-purin-2-yl)benzamide.

N-(9-((2R,3R,4R,5R)-4-Hydroxy-5-(hydroxymethyl)-3-((4-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-1H-purin-2-yl)benzamide (CAS 60943-92-2) is a high-purity analytical reference standard with the molecular formula C23H27N5O8 and a molecular weight of 501.49 g/mol.

The molecular framework of N-(9-((2R,3R,4R,5R)-4-Hydroxy-5-(hydroxymethyl)-3-((4-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-1H-purin-2-yl)benzamide (C23H27N5O8) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
