2-(5-Methoxy-1-methyl-2,4-dioxo-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)-N-propylacetamide CAS 921490-20-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-Methoxy-1-methyl-2,4-dioxo-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)-N-propylacetamide.

2-(5-Methoxy-1-methyl-2,4-dioxo-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)-N-propylacetamide (CAS 921490-20-2) is a high-purity analytical reference standard with the molecular formula C14H18N4O4 and a molecular weight of 306.32 g/mol.

The molecular framework of 2-(5-Methoxy-1-methyl-2,4-dioxo-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)-N-propylacetamide (C14H18N4O4) 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).

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), 2-(5-Methoxy-1-methyl-2,4-dioxo-1,4-dihydropyrido[2,3-d]pyrimidin-3(2H)-yl)-N-propylacetamide 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.
