Chemical Structure
Description
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.
N4,N4,N4',N4'-Tetrakis(4-bromophenyl)-[1,1'-biphenyl]-4,4'-diamine (CAS 113664-24-7), molecular formula C36H24Br4N2 and molecular weight 804.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N4,N4,N4',N4'-Tetrakis(4-bromophenyl)-[1,1'-biphenyl]-4,4'-diamine (C36H24Br4N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
