(2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-5-(2-isobutyramido-6-oxo-1,6-dihydro-9H-purin-9-yl)-4-(2-methoxyethoxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (CAS 251647-55-9), molecular formula C47H60N7O10P and molecular weight 913.99 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, (2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-5-(2-isobutyramido-6-oxo-1,6-dihydro-9H-purin-9-yl)-4-(2-methoxyethoxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 913.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
