Description

Compared with other compounds in its class, the molecular weight of 204.25 g/mol gives 1-methyl-3-(3-sulfonatopropyl)-1H-imidazol-3-ium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-methyl-3-(3-sulfonatopropyl)-1H-imidazol-3-ium (CAS 148019-49-2), a certified reference material (molecular formula C7H12N2O3S, MW 204.25 g/mol) for analytical method development and quality control.

1-methyl-3-(3-sulfonatopropyl)-1H-imidazol-3-ium (C7H12N2O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-methyl-3-(3-sulfonatopropyl)-1H-imidazol-3-ium 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.
