As a certified reference material (CRM), Ethyl 2-((2-methyl-5-nitrobenzyl)thio)-1H-benzo[d]imidazole-1-carboxylate 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.
Ethyl 2-((2-methyl-5-nitrobenzyl)thio)-1H-benzo[d]imidazole-1-carboxylate (CAS 845879-36-9) is a high-purity analytical reference standard with the molecular formula C18H17N3O4S and a molecular weight of 371.41 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-((2-methyl-5-nitrobenzyl)thio)-1H-benzo[d]imidazole-1-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
