Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
5,6-Dichloro-2-(2-chloropyridin-3-yl)-1-methyl-1H-benzo[d]imidazole (CAS 861208-45-9), molecular formula C13H8Cl3N3 and molecular weight 312.58 g/mol, is a CATO reference standard with documented purity and traceability.
5,6-Dichloro-2-(2-chloropyridin-3-yl)-1-methyl-1H-benzo[d]imidazole (C13H8Cl3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
