Compared with other compounds in its class, the molecular weight of 315.16 g/mol gives 5-Bromo-1-cyclohexyl-6,7-difluorobenzimidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-1-cyclohexyl-6,7-difluorobenzimidazole (CAS 1365271-96-0) is a high-purity analytical reference standard with the molecular formula C13H13BrF2N2 and a molecular weight of 315.16 g/mol.
The molecular framework of 5-Bromo-1-cyclohexyl-6,7-difluorobenzimidazole (C13H13BrF2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
