1,4-Bis(2,6-dimethylpyridin-4-yl)benzene (CAS 851868-26-3), molecular formula C20H20N2 and molecular weight 288.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,4-Bis(2,6-dimethylpyridin-4-yl)benzene (C20H20N2) 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.
