2,3,4-Trichloro-N-(5,6-dimethyl-1-(3-methylbenzyl)-1H-benzo[d]imidazol-4-yl)benzenesulfonamide CAS 338423-59-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 508.85 g/mol gives 2,3,4-Trichloro-N-(5,6-dimethyl-1-(3-methylbenzyl)-1H-benzo[d]imidazol-4-yl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3,4-Trichloro-N-(5,6-dimethyl-1-(3-methylbenzyl)-1H-benzo[d]imidazol-4-yl)benzenesulfonamide (CAS 338423-59-9) is a high-purity analytical reference standard with the molecular formula C23H20Cl3N3O2S and a molecular weight of 508.85 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2,3,4-Trichloro-N-(5,6-dimethyl-1-(3-methylbenzyl)-1H-benzo[d]imidazol-4-yl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 508.85 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), 2,3,4-Trichloro-N-(5,6-dimethyl-1-(3-methylbenzyl)-1H-benzo[d]imidazol-4-yl)benzenesulfonamide 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.
