Description
As a certified reference material (CRM), 2-Fluorophenyl 5-chloro-2-(methylthio)pyrimidine-4-carboxylate 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.
CATO supplies 2-Fluorophenyl 5-chloro-2-(methylthio)pyrimidine-4-carboxylate (CAS 879947-99-6), a certified reference material (molecular formula C12H8ClFN2O2S, MW 298.72 g/mol) for analytical method development and quality control.
2-Fluorophenyl 5-chloro-2-(methylthio)pyrimidine-4-carboxylate (C12H8ClFN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
