(2R,3R,4R,5R)-2-(4-Isobutyramido-2-oxopyrimidin-1(2H)-yl)-5-((isobutyryloxy)methyl)tetrahydrofuran-3,4-diyl bis(2-methylpropanoate) (Molnupiravir Impurity) (CAS 863592-00-1) is a high-purity analytical reference standard with the molecular formula C25H37N3O9 and a molecular weight of 523.58 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (2R,3R,4R,5R)-2-(4-Isobutyramido-2-oxopyrimidin-1(2H)-yl)-5-((isobutyryloxy)methyl)tetrahydrofuran-3,4-diyl bis(2-methylpropanoate) (Molnupiravir Impurity) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 523.58 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).
CATO manufactures (2R,3R,4R,5R)-2-(4-Isobutyramido-2-oxopyrimidin-1(2H)-yl)-5-((isobutyryloxy)methyl)tetrahydrofuran-3,4-diyl bis(2-methylpropanoate) (Molnupiravir Impurity) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
