Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N,N'-Bis(9,9-dimethyl-9H-fluoren-2-yl)-N,N'-diphenylbenzidine (CAS 361486-60-4), molecular formula C54H44N2 and molecular weight 720.94 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N,N'-Bis(9,9-dimethyl-9H-fluoren-2-yl)-N,N'-diphenylbenzidine (C54H44N2) 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).

As a certified reference material (CRM), N,N'-Bis(9,9-dimethyl-9H-fluoren-2-yl)-N,N'-diphenylbenzidine 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.
