4-Methyl-2-(4-(4-(pyrimidin-2-yl)piperazin-1-yl)butyl)-1,2,4-triazine-3,5(2H,4H)-dione (CAS 179756-58-2), molecular formula C16H23N7O2 and molecular weight 345.40 g/mol, is a CATO reference standard with documented purity and traceability.
4-Methyl-2-(4-(4-(pyrimidin-2-yl)piperazin-1-yl)butyl)-1,2,4-triazine-3,5(2H,4H)-dione (C16H23N7O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-Methyl-2-(4-(4-(pyrimidin-2-yl)piperazin-1-yl)butyl)-1,2,4-triazine-3,5(2H,4H)-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.
