Chemical Structure
Description
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.
5'-O-[Bis(4-methoxyphenyl)phenylmethyl]-2'-deoxy-2'-fluoro-5-methyluridine (CAS 133324-02-4), molecular formula C31H31FN2O7 and molecular weight 562.59 g/mol, is a CATO reference standard with documented purity and traceability.
5'-O-[Bis(4-methoxyphenyl)phenylmethyl]-2'-deoxy-2'-fluoro-5-methyluridine (C31H31FN2O7) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 5'-O-[Bis(4-methoxyphenyl)phenylmethyl]-2'-deoxy-2'-fluoro-5-methyluridine 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.
