Description

N-(9-((2R,3R,4R,5R)-3-((tert-Butyldimethylsilyl)oxy)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-1H-purin-2-yl)benzamide (CAS 72409-43-9) is a high-purity analytical reference standard with the molecular formula C23H31N5O6Si and a molecular weight of 501.61 g/mol.

Structurally, N-(9-((2R,3R,4R,5R)-3-((tert-Butyldimethylsilyl)oxy)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-1H-purin-2-yl)benzamide (C23H31N5O6Si) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 501.61 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).

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.
