Description
As a certified reference material (CRM), 1-Benzyl-2-(6-chloropyridin-3-yl)-5,6-dimethyl-1H-1,3-benzodiazole 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.
1-Benzyl-2-(6-chloropyridin-3-yl)-5,6-dimethyl-1H-1,3-benzodiazole (CAS 337920-59-9), molecular formula C21H18ClN3 and molecular weight 347.84 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Benzyl-2-(6-chloropyridin-3-yl)-5,6-dimethyl-1H-1,3-benzodiazole (C21H18ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 347.84 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.
