N-[4-(4-fluorophenyl)-1H-imidazol-2-yl]acetamide (CAS 910443-44-6) is a high-purity analytical reference standard with the molecular formula C11H10FN3O and a molecular weight of 219.22 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, N-[4-(4-fluorophenyl)-1H-imidazol-2-yl]acetamide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 219.22 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.
As a certified reference material (CRM), N-[4-(4-fluorophenyl)-1H-imidazol-2-yl]acetamide 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.
