Chemical Structure
Description
5,6-Dibromo-3-((4-fluoro-3-nitrophenyl)amino)-1-methylpyrazin-2(1H)-one (CAS CATO-CIM-105246) is a high-purity analytical reference standard with the molecular formula C11H7Br2FN4O3 and a molecular weight of 422.00 g/mol.
Structurally, 5,6-Dibromo-3-((4-fluoro-3-nitrophenyl)amino)-1-methylpyrazin-2(1H)-one (C11H7Br2FN4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 422.00 g/mol, it falls into the moderately-high-molecular-weight range. 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.
