Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 9,9''-Diphenyl-9H,9'H,9''H-3,2':7',3''-tercarbazole (CAS 1402543-31-0), a certified reference material (molecular formula C48H31N3, MW 649.78 g/mol) for analytical method development and quality control.
Structurally, 9,9''-Diphenyl-9H,9'H,9''H-3,2':7',3''-tercarbazole (C48H31N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 35.0, corresponding to approximately 35 ring(s) or double-bond equivalent(s). With a molecular weight of 649.78 g/mol, it falls into the 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).
As a certified reference material (CRM), 9,9''-Diphenyl-9H,9'H,9''H-3,2':7',3''-tercarbazole 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.
