Chemical Structure

1-(3-Bromophenyl)-2-(4,5-dichloro-1H-imidazol-1-yl)ethan-1-one CAS 634154-99-7 chemical structure

Description

The occurrence of 1-(3-Bromophenyl)-2-(4,5-dichloro-1H-imidazol-1-yl)ethan-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3-Bromophenyl)-2-(4,5-dichloro-1H-imidazol-1-yl)ethan-1-one (CAS 634154-99-7) is a high-purity analytical reference standard with the molecular formula C11H7BrCl2N2O and a molecular weight of 334.00 g/mol.

1-(3-Bromophenyl)-2-(4,5-dichloro-1H-imidazol-1-yl)ethan-1-one (C11H7BrCl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
