Chemical Structure
Description
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.
2-(4-Bromophenyl)-1-phenyl-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide (CAS 478959-75-0) is a high-purity analytical reference standard with the molecular formula C20H20BrN2Br and a molecular weight of 448.20 g/mol.
Structurally, 2-(4-Bromophenyl)-1-phenyl-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide (C20H20BrN2Br) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 448.20 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.
