Chemical Structure

N,N'-([1,1'-biphenyl]-4,4'-diyl)bis(1-phenylmethanimine) CAS 6311-48-4 chemical structure

Description

N,N'-([1,1'-biphenyl]-4,4'-diyl)bis(1-phenylmethanimine) (CAS 6311-48-4), molecular formula C26H20N2 and molecular weight 360.45 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N,N'-([1,1'-biphenyl]-4,4'-diyl)bis(1-phenylmethanimine) (C26H20N2) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
