6-Amino-3-methyl-5-nitropyrimidine-2,4(3H,5H)-dione CAS 448904-31-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Amino-3-methyl-5-nitropyrimidine-2,4(3H,5H)-dione.

6-Amino-3-methyl-5-nitropyrimidine-2,4(3H,5H)-dione (CAS 448904-31-2), molecular formula C5H6N4O4 and molecular weight 186.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Amino-3-methyl-5-nitropyrimidine-2,4(3H,5H)-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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
