Chemical Structure
Description
5,5'-Dimethyl-[4,4'-bipyrimidine]-2,2',6(1H,3H,3'H)-trione (CAS 20545-68-0) is a high-purity analytical reference standard with the molecular formula C10H10N4O3 and a molecular weight of 234.21 g/mol.
The molecular framework of 5,5'-Dimethyl-[4,4'-bipyrimidine]-2,2',6(1H,3H,3'H)-trione (C10H10N4O3) 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.
As a certified reference material (CRM), 5,5'-Dimethyl-[4,4'-bipyrimidine]-2,2',6(1H,3H,3'H)-trione 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.
