Chemical Structure
Description
Methyl 4-[4-(tert-butyl)phenyl]-6-(2-methoxy-2-oxoethyl)-2-oxo-1,2,3,4-tetrahydro-5-pyrimidinecarboxylate (CAS 952183-65-2), molecular formula C19H24N2O5 and molecular weight 360.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 4-[4-(tert-butyl)phenyl]-6-(2-methoxy-2-oxoethyl)-2-oxo-1,2,3,4-tetrahydro-5-pyrimidinecarboxylate (C19H24N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Methyl 4-[4-(tert-butyl)phenyl]-6-(2-methoxy-2-oxoethyl)-2-oxo-1,2,3,4-tetrahydro-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.
