5,6-Dichloro-2-(2-chloropyridin-3-yl)-1-(3-fluorobenzyl)-1H-benzo[d]imidazole (CAS 338774-12-2), molecular formula C19H11Cl3FN3 and molecular weight 406.67 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5,6-Dichloro-2-(2-chloropyridin-3-yl)-1-(3-fluorobenzyl)-1H-benzo[d]imidazole (C19H11Cl3FN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 406.67 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
