Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 213.06 g/mol gives 1-(3,4-Dichlorophenyl)-1H-imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(3,4-Dichlorophenyl)-1H-imidazole (CAS 90225-41-5), a certified reference material (molecular formula C9H6Cl2N2, MW 213.06 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-(3,4-Dichlorophenyl)-1H-imidazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 1-(3,4-Dichlorophenyl)-1H-imidazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
