Chemical Structure
Description
The molecular framework of 5-Amino-2-(dimethylamino)-6-(methylamino)pyrimidin-4(1H)-one (C7H13N5O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
5-Amino-2-(dimethylamino)-6-(methylamino)pyrimidin-4(1H)-one (CAS 61693-35-4) is a high-purity analytical reference standard with the molecular formula C7H13N5O and a molecular weight of 183.21 g/mol.
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), 5-Amino-2-(dimethylamino)-6-(methylamino)pyrimidin-4(1H)-one 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.
