Chemical Structure
Description
1-((2,3,5,6-Tetramethylphenyl)sulfonyl)-1H-imidazole (CAS 898644-38-7) is a high-purity analytical reference standard with the molecular formula C13H16N2O2S and a molecular weight of 264.34 g/mol.
1-((2,3,5,6-Tetramethylphenyl)sulfonyl)-1H-imidazole (C13H16N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1-((2,3,5,6-Tetramethylphenyl)sulfonyl)-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.
