Chemical Structure

6-Chloro-1H-benzo[d]imidazole-5-sulfonamide CAS 89725-01-9 chemical structure

Description

The occurrence of 6-Chloro-1H-benzo[d]imidazole-5-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Chloro-1H-benzo[d]imidazole-5-sulfonamide (CAS 89725-01-9), molecular formula C7H6ClN3O2S and molecular weight 231.66 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, chlorine substitution, an aromatic ring system, 6-Chloro-1H-benzo[d]imidazole-5-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.66 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), 6-Chloro-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.
