Description

The occurrence of (2R,3R,4R,5R)-5-(4-Benzamido-5-methyl-2-oxopyrimidin-1(2H)-yl)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-(2-methoxyethoxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2R,3R,4R,5R)-5-(4-Benzamido-5-methyl-2-oxopyrimidin-1(2H)-yl)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-(2-methoxyethoxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (CAS 163759-94-2) is a high-purity analytical reference standard with the molecular formula C50H60N5O10P and a molecular weight of 922.01 g/mol.

The molecular framework of (2R,3R,4R,5R)-5-(4-Benzamido-5-methyl-2-oxopyrimidin-1(2H)-yl)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-(2-methoxyethoxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (C50H60N5O10P) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), (2R,3R,4R,5R)-5-(4-Benzamido-5-methyl-2-oxopyrimidin-1(2H)-yl)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-(2-methoxyethoxy)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.
