Chemical Structure
Description
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.
CATO supplies 1-((3-Bromo-5-(trifluoromethyl)phenyl)sulfonyl)-2-methyl-1H-imidazole (CAS 951884-57-4), a certified reference material (molecular formula C11H8BrF3N2O2S, MW 369.16 g/mol) for analytical method development and quality control.
Structurally, 1-((3-Bromo-5-(trifluoromethyl)phenyl)sulfonyl)-2-methyl-1H-imidazole (C11H8BrF3N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 369.16 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 1-((3-Bromo-5-(trifluoromethyl)phenyl)sulfonyl)-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.
