The occurrence of N4,N4,N4',N4'-Tetra(naphthalen-1-yl)-[1,1'-biphenyl]-4,4'-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.
N4,N4,N4',N4'-Tetra(naphthalen-1-yl)-[1,1'-biphenyl]-4,4'-diamine (CAS 186256-01-9), molecular formula C52H36N2 and molecular weight 688.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N4,N4,N4',N4'-Tetra(naphthalen-1-yl)-[1,1'-biphenyl]-4,4'-diamine (C52H36N2) 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.
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.
