Chemical Structure
Description
1-(4-Iodophenyl)-2-methyl-1H-imidazole (CAS 179420-75-8), molecular formula C10H9IN2 and molecular weight 284.10 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Iodophenyl)-2-methyl-1H-imidazole (C10H9IN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-(4-Iodophenyl)-2-methyl-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.
