(2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-((tert-butyldimethylsilyl)oxy)-5-(6-(methylamino)-9H-purin-9-yl)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (CAS 588698-79-7) is a high-purity analytical reference standard with the molecular formula C47H64N7O7PSi and a molecular weight of 898.11 g/mol.
Structurally, (2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-((tert-butyldimethylsilyl)oxy)-5-(6-(methylamino)-9H-purin-9-yl)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (C47H64N7O7PSi) 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 19.5, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 898.11 g/mol, it falls into the 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.
