2,4,6-Tri(pyridin-4-yl)aniline (CAS 2258656-65-2) is a high-purity analytical reference standard with the molecular formula C21H16N4 and a molecular weight of 324.38 g/mol.
The molecular framework of 2,4,6-Tri(pyridin-4-yl)aniline (C21H16N4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
