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'-(3,6-dibromopyrazin-2-yl)-n,n-dimethyl-formamidine.
N'-(3,6-dibromopyrazin-2-yl)-n,n-dimethyl-formamidine (CAS 959755-42-1) is a high-purity analytical reference standard with the molecular formula C7H8Br2N4 and a molecular weight of 307.97 g/mol.
Based on its molecular formula C7H8Br2N4, N'-(3,6-dibromopyrazin-2-yl)-n,n-dimethyl-formamidine contains a nitrile group, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 307.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
