1-Benzyl-2,3,5,6-tetraphenylpyridin-1-ium tetrafluoroborate (CAS 71670-95-6), molecular formula C36H28NBF4 and molecular weight 561.43 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 1-Benzyl-2,3,5,6-tetraphenylpyridin-1-ium tetrafluoroborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 561.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), 1-Benzyl-2,3,5,6-tetraphenylpyridin-1-ium tetrafluoroborate 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.
