Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 4-[4-(2-fluorophenyl)piperazino]-2-(methylsulfanyl)-5-pyrimidinecarboxylate (CAS 339019-52-2), molecular formula C18H21FN4O2S and molecular weight 376.45 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 4-[4-(2-fluorophenyl)piperazino]-2-(methylsulfanyl)-5-pyrimidinecarboxylate (C18H21FN4O2S) contains a steroid 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.
As a certified reference material (CRM), Ethyl 4-[4-(2-fluorophenyl)piperazino]-2-(methylsulfanyl)-5-pyrimidinecarboxylate 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.
