Chemical Structure
Description
The molecular framework of N,N'-bis(2,4,6-trimethylphenyl)ethane-1,2-diamine,dihydrochloride (C20H28N2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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 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).
N,N'-bis(2,4,6-trimethylphenyl)ethane-1,2-diamine,dihydrochloride (CAS 258278-23-8), molecular formula C20H28N2HCl and molecular weight 332.92 g/mol, is a CATO reference standard with documented purity and traceability.
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.
