Chemical Structure

1,2,4,5-Tetrakis(4-cyanophenyl)benzene CAS 633300-89-7 chemical structure

Description

The molecular framework of 1,2,4,5-Tetrakis(4-cyanophenyl)benzene (C34H18N4) 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.

1,2,4,5-Tetrakis(4-cyanophenyl)benzene (CAS 633300-89-7) is a high-purity analytical reference standard with the molecular formula C34H18N4 and a molecular weight of 482.53 g/mol.

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.
