Description

Structurally, N-[9-[(2R,4S,5R)-5-[[bis(4-methoxyphenyl)-phenyl-methoxy]methyl]-4-[2-cyanoethoxy-(diisopropylamino)phosphanyl]oxy-tetrahydrofuran-2-yl]-8-hydroxy-6-oxo-5H-purin-2-yl]-2-methyl-propanamide (C44H72N7O9P) 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 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 874.06 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies N-[9-[(2R,4S,5R)-5-[[bis(4-methoxyphenyl)-phenyl-methoxy]methyl]-4-[2-cyanoethoxy-(diisopropylamino)phosphanyl]oxy-tetrahydrofuran-2-yl]-8-hydroxy-6-oxo-5H-purin-2-yl]-2-methyl-propanamide (CAS 143060-53-1), a certified reference material (molecular formula C44H72N7O9P, MW 874.06 g/mol) for analytical method development and quality control.

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.
