Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(2R,3R,4R,5R)-2-[[bis(4-methoxyphenyl)-phenyl-methoxy]methyl]-5-(2,4-dioxopyrimidin-1-yl)-4-fluoro-tetrahydrofuran-3-yl]oxy-4-oxo-butanoic acid.

4-[(2R,3R,4R,5R)-2-[[bis(4-methoxyphenyl)-phenyl-methoxy]methyl]-5-(2,4-dioxopyrimidin-1-yl)-4-fluoro-tetrahydrofuran-3-yl]oxy-4-oxo-butanoic acid (CAS 2294880-67-2), molecular formula C34H53FN2O10 and molecular weight 668.79 g/mol, is a CATO reference standard with documented purity and traceability.

4-[(2R,3R,4R,5R)-2-[[bis(4-methoxyphenyl)-phenyl-methoxy]methyl]-5-(2,4-dioxopyrimidin-1-yl)-4-fluoro-tetrahydrofuran-3-yl]oxy-4-oxo-butanoic acid (C34H53FN2O10) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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.

As a certified reference material (CRM), 4-[(2R,3R,4R,5R)-2-[[bis(4-methoxyphenyl)-phenyl-methoxy]methyl]-5-(2,4-dioxopyrimidin-1-yl)-4-fluoro-tetrahydrofuran-3-yl]oxy-4-oxo-butanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
