Chemical Structure
Description
Ethyl 4-(4-Fluorophenyl)-6-isopropyl-2-(methylsulfonyl)pyrimidine- 5-carboxylate-d6 (C17H13D6FN2O4S) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Ethyl 4-(4-Fluorophenyl)-6-isopropyl-2-(methylsulfonyl)pyrimidine- 5-carboxylate-d6 (CAS 1185128-49-7), molecular formula C17H13D6FN2O4S and molecular weight 372.44 g/mol, is a CATO reference standard with documented purity and traceability.
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), Ethyl 4-(4-Fluorophenyl)-6-isopropyl-2-(methylsulfonyl)pyrimidine- 5-carboxylate-d6 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.
