CATO supplies 1-((4-Chloro-3-methoxyphenyl)sulfonyl)-2-ethyl-4-methyl-1H-imidazole (CAS 898656-19-4), a certified reference material (molecular formula C13H15ClN2O3S, MW 314.79 g/mol) for analytical method development and quality control.
Structurally, 1-((4-Chloro-3-methoxyphenyl)sulfonyl)-2-ethyl-4-methyl-1H-imidazole (C13H15ClN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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 314.79 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
