Description

The occurrence of 9,9,9',9',9'',9''-Hexamethyl-N7,N7''-diphenyl-N7,N7''-di-m-tolyl-9H,9'H,9''H-[2,2':7',2''-terfluorene]-7,7''-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

9,9,9',9',9'',9''-Hexamethyl-N7,N7''-diphenyl-N7,N7''-di-m-tolyl-9H,9'H,9''H-[2,2':7',2''-terfluorene]-7,7''-diamine (CAS 239476-24-5), molecular formula C71H60N2 and molecular weight 941.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 9,9,9',9',9'',9''-Hexamethyl-N7,N7''-diphenyl-N7,N7''-di-m-tolyl-9H,9'H,9''H-[2,2':7',2''-terfluorene]-7,7''-diamine (C71H60N2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 9,9,9',9',9'',9''-Hexamethyl-N7,N7''-diphenyl-N7,N7''-di-m-tolyl-9H,9'H,9''H-[2,2':7',2''-terfluorene]-7,7''-diamine 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.
