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 N'-(3,5-Dibromopyrazin-2-yl)-N-hydroxyformimidamide.
N'-(3,5-Dibromopyrazin-2-yl)-N-hydroxyformimidamide (CAS 60420-05-5), molecular formula C5H4Br2N4O and molecular weight 295.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N'-(3,5-Dibromopyrazin-2-yl)-N-hydroxyformimidamide (C5H4Br2N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
