5,10-Dihydroxy-2,8-dimethylpyrimido[5,4-g]quinazoline-4,6(1H,7H)-dione (CAS 115705-72-1) is a high-purity analytical reference standard with the molecular formula C12H10N4O4 and a molecular weight of 274.23 g/mol.
The molecular framework of 5,10-Dihydroxy-2,8-dimethylpyrimido[5,4-g]quinazoline-4,6(1H,7H)-dione (C12H10N4O4) 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).
As a certified reference material (CRM), 5,10-Dihydroxy-2,8-dimethylpyrimido[5,4-g]quinazoline-4,6(1H,7H)-dione 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.
