Chemical Structure
Description
1-(2-Methoxyethyl)-1H-imidazole-2-sulfonamide (CAS 89517-94-2), molecular formula C6H11N3O3S and molecular weight 205.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1-(2-Methoxyethyl)-1H-imidazole-2-sulfonamide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 1-(2-Methoxyethyl)-1H-imidazole-2-sulfonamide 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.
