(2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-5-(5-bromo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-4-((tert-butyldimethylsilyl)oxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite CAS 166733-98-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-5-(5-bromo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-4-((tert-butyldimethylsilyl)oxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite.

CATO supplies (2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-5-(5-bromo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-4-((tert-butyldimethylsilyl)oxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (CAS 166733-98-8), a certified reference material (molecular formula C45H60BrN4O9PSi, MW 939.94 g/mol) for analytical method development and quality control.

The molecular framework of (2R,3R,4R,5R)-2-((Bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-5-(5-bromo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-4-((tert-butyldimethylsilyl)oxy)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite (C45H60BrN4O9PSi) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, bromine substitution. 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 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
