Description
Compared with other compounds in its class, the molecular weight of 242.70 g/mol gives Ethyl 4-(tert-butyl)-2-chloropyrimidine-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4-(tert-butyl)-2-chloropyrimidine-5-carboxylate (CAS 863323-33-5) is a high-purity analytical reference standard with the molecular formula C11H15ClN2O2 and a molecular weight of 242.70 g/mol.
Ethyl 4-(tert-butyl)-2-chloropyrimidine-5-carboxylate (C11H15ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 4-(tert-butyl)-2-chloropyrimidine-5-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.
