Chemical Structure

4,4'-Methylenebis(3-methylaniline) CAS 97-28-9 chemical structure

Description

Based on its molecular formula C15H18N2, 4,4'-Methylenebis(3-methylaniline) contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

4,4'-Methylenebis(3-methylaniline) (CAS 97-28-9) is a high-purity analytical reference standard with the molecular formula C15H18N2 and a molecular weight of 226.32 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.
