Chemical Structure
Description
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.
6-(Methylamino)-5-nitropyrimidine-2,4(1H,3H)-dione (CAS 41964-42-5) is a high-purity analytical reference standard with the molecular formula C5H6N4O4 and a molecular weight of 186.13 g/mol.
The molecular framework of 6-(Methylamino)-5-nitropyrimidine-2,4(1H,3H)-dione (C5H6N4O4) is characterized by a carbohydrate-derived structure, an amide group. 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).
As a certified reference material (CRM), 6-(Methylamino)-5-nitropyrimidine-2,4(1H,3H)-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.
