2-(1-Methyl-2,4-dioxo-5-propoxy-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)acetamide (CAS 921480-54-8), molecular formula C13H16N4O4 and molecular weight 292.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(1-Methyl-2,4-dioxo-5-propoxy-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)acetamide (C13H16N4O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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), 2-(1-Methyl-2,4-dioxo-5-propoxy-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)acetamide 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.
