N-(2,6-Dihydroxypyrimidin-4-yl)-1H-1,2,4-triazole-3-carboxamide CAS 709018-26-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,6-Dihydroxypyrimidin-4-yl)-1H-1,2,4-triazole-3-carboxamide.

N-(2,6-Dihydroxypyrimidin-4-yl)-1H-1,2,4-triazole-3-carboxamide (CAS 709018-26-8), molecular formula C7H6N6O3 and molecular weight 222.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, N-(2,6-Dihydroxypyrimidin-4-yl)-1H-1,2,4-triazole-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
