Chemical Structure

2-Methyl-1h-benzo[d]imidazole-5-sulfonamide CAS 57476-34-3 chemical structure

Description

As a certified reference material (CRM), 2-Methyl-1h-benzo[d]imidazole-5-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.

CATO supplies 2-Methyl-1h-benzo[d]imidazole-5-sulfonamide (CAS 57476-34-3), a certified reference material (molecular formula C8H9N3O2S, MW 211.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H9N3O2S, 2-Methyl-1h-benzo[d]imidazole-5-sulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 211.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
