N,N-di([1,1'-biphenyl]-4-yl)-9,9-diphenyl-9H-fluoren-4-amine CAS 1547491-36-0

Description

Compared with other compounds in its class, the molecular weight of 637.81 g/mol gives N,N-di([1,1'-biphenyl]-4-yl)-9,9-diphenyl-9H-fluoren-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N,N-di([1,1'-biphenyl]-4-yl)-9,9-diphenyl-9H-fluoren-4-amine (CAS 1547491-36-0) is a high-purity analytical reference standard with the molecular formula C49H35N and a molecular weight of 637.81 g/mol.

The molecular framework of N,N-di([1,1'-biphenyl]-4-yl)-9,9-diphenyl-9H-fluoren-4-amine (C49H35N) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
