Description

As a certified reference material (CRM), (2R,3S,5R)-5-(4-Benzamido-5-((2-cyanoethoxy)methyl)-2-oxopyrimidin-1(2H)-yl)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(2R,3S,5R)-5-(4-Benzamido-5-((2-cyanoethoxy)methyl)-2-oxopyrimidin-1(2H)-yl)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (CAS 188411-06-5) is a high-purity analytical reference standard with the molecular formula C50H57N6O9P and a molecular weight of 917.00 g/mol.

Structurally, (2R,3S,5R)-5-(4-Benzamido-5-((2-cyanoethoxy)methyl)-2-oxopyrimidin-1(2H)-yl)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (C50H57N6O9P) 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 25.5, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 917.00 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.
