Chemical Structure
Description
3-(5,6-Dichloro-1-(2-chloro-6-fluorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one (CAS 338774-13-3) is a high-purity analytical reference standard with the molecular formula C19H11Cl3FN3O and a molecular weight of 422.67 g/mol.
3-(5,6-Dichloro-1-(2-chloro-6-fluorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one (C19H11Cl3FN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-(5,6-Dichloro-1-(2-chloro-6-fluorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one 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.
