Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 237.10 g/mol gives 1-(4-Bromobenzyl)imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-Bromobenzyl)imidazole (CAS 72459-46-2) is a high-purity analytical reference standard with the molecular formula C10H9BrN2 and a molecular weight of 237.10 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 1-(4-Bromobenzyl)imidazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
