(2R,3R,4R,5R)-2-(4-Benzamido-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-((tert-butyldimethylsilyl)oxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphorami (CAS 2243079-18-5), molecular formula C54H67N6O8PSi and molecular weight 987.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R,3R,4R,5R)-2-(4-Benzamido-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-((tert-butyldimethylsilyl)oxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphorami (C54H67N6O8PSi) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), (2R,3R,4R,5R)-2-(4-Benzamido-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-((tert-butyldimethylsilyl)oxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphorami 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.
