Chemical Structure
Description
As a certified reference material (CRM), 6-Chloro-2-propyl-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.
6-Chloro-2-propyl-1H-benzo[d]imidazole-5-sulfonamide (CAS 89725-06-4) is a high-purity analytical reference standard with the molecular formula C10H12ClN3O2S and a molecular weight of 273.74 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-2-propyl-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 273.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
