Chemical Structure

2,6-Diamino-5-nitropyrimidine-4-carboxamide CAS 19796-69-1 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 2,6-Diamino-5-nitropyrimidine-4-carboxamide.

2,6-Diamino-5-nitropyrimidine-4-carboxamide (CAS 19796-69-1), molecular formula C5H6N6O3 and molecular weight 198.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,6-Diamino-5-nitropyrimidine-4-carboxamide (C5H6N6O3) is characterized by an amino-acid-derived structure, 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 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.

CATO manufactures 2,6-Diamino-5-nitropyrimidine-4-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
