N1,N1'-([1,1'-Biphenyl]-4,4'-diyl)bis(N1-phenyl-N4,N4-di-p-tolylbenzene-1,4-diamine) CAS 1394130-64-3

Description

The molecular framework of N1,N1'-([1,1'-Biphenyl]-4,4'-diyl)bis(N1-phenyl-N4,N4-di-p-tolylbenzene-1,4-diamine) (C64H54N4) 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).

N1,N1'-([1,1'-Biphenyl]-4,4'-diyl)bis(N1-phenyl-N4,N4-di-p-tolylbenzene-1,4-diamine) (CAS 1394130-64-3), molecular formula C64H54N4 and molecular weight 879.14 g/mol, is a CATO reference standard with documented purity and traceability.
