Chemical Structure
Description
As a certified reference material (CRM), 4,6-Diphenyl-2,2'-bipyridine 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.
CATO supplies 4,6-Diphenyl-2,2'-bipyridine (CAS 57476-59-2), a certified reference material (molecular formula C22H16N2, MW 308.38 g/mol) for analytical method development and quality control.
Structurally, 4,6-Diphenyl-2,2'-bipyridine (C22H16N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 308.38 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.
