Chemical Structure
Description
As a certified reference material (CRM), Ethyl 6-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-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.
Ethyl 6-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (CAS 22293-59-0), molecular formula C8H10N2O4 and molecular weight 198.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 6-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (C8H10N2O4) is characterized by an amino-acid-derived structure, 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.
