CATO supplies (2R,3R,4R,5R)-5-((Benzoyloxy)Methyl)-2-(2,4-Dioxo-3,4-Dihydropyrimidin-1(2H)-Yl)-3-Ethynyltetrahydrofuran-3,4-Diyl Dibenzoate (CAS 1443997-55-4), a certified reference material (molecular formula C32H24N2O9, MW 580.54 g/mol) for analytical method development and quality control.
(2R,3R,4R,5R)-5-((Benzoyloxy)Methyl)-2-(2,4-Dioxo-3,4-Dihydropyrimidin-1(2H)-Yl)-3-Ethynyltetrahydrofuran-3,4-Diyl Dibenzoate (C32H24N2O9) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
