Compared with other compounds in its class, the molecular weight of 290.36 g/mol gives 5,5',6,6'-Tetramethyl-1H,1'H-2,2'-bibenzo[d]imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,5',6,6'-Tetramethyl-1H,1'H-2,2'-bibenzo[d]imidazole (CAS 14468-52-1), molecular formula C18H18N4 and molecular weight 290.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,5',6,6'-Tetramethyl-1H,1'H-2,2'-bibenzo[d]imidazole (C18H18N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 5,5',6,6'-Tetramethyl-1H,1'H-2,2'-bibenzo[d]imidazole 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.
