Chemical Structure
Description
((2R,3S,5R)-5-(6-Bromo-5-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (CAS 189688-12-8) is a high-purity analytical reference standard with the molecular formula C10H14BrN2O8P and a molecular weight of 401.10 g/mol.
((2R,3S,5R)-5-(6-Bromo-5-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (C10H14BrN2O8P) contains a carbohydrate-derived structure, an amide group, a phosphate ester group, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures ((2R,3S,5R)-5-(6-Bromo-5-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-3-hydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate 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.
