Chemical Structure

4,4'-((1E,1'E)-9,9'-Spirobi[fluorene]-2,7-diylbis(ethene-2,1-diyl))bis(N,N-diphenylaniline) CAS 436798-89-9 chemical structure

Description

As a certified reference material (CRM), 4,4'-((1E,1'E)-9,9'-Spirobi[fluorene]-2,7-diylbis(ethene-2,1-diyl))bis(N,N-diphenylaniline) 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 4,4'-((1E,1'E)-9,9'-Spirobi[fluorene]-2,7-diylbis(ethene-2,1-diyl))bis(N,N-diphenylaniline) (CAS 436798-89-9), a certified reference material (molecular formula C65H46N2, MW 855.07 g/mol) for analytical method development and quality control.

The molecular framework of 4,4'-((1E,1'E)-9,9'-Spirobi[fluorene]-2,7-diylbis(ethene-2,1-diyl))bis(N,N-diphenylaniline) (C65H46N2) 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).

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