Chemical Structure
Description
1-(3,4-Dichlorophenyl)-2,4,6(1H,3H,5H)-pyrimidinetrione (CAS 340300-14-3), molecular formula C10H6Cl2N2O3 and molecular weight 273.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3,4-Dichlorophenyl)-2,4,6(1H,3H,5H)-pyrimidinetrione (C10H6Cl2N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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), 1-(3,4-Dichlorophenyl)-2,4,6(1H,3H,5H)-pyrimidinetrione 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.
