General description

4,4′-Methylene-bis(2-methylaniline) belongs to the primary aromatic amines (PAAs) family of compounds which are toxic in nature and are probable human carcinogens.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)

Application

4,4′-Methylene-bis(2-methylaniline) has been used as a reference standard for the determination of 4,4′-methylene-bis(2-methylaniline) in plastic multilayer food packaging materials by liquid chromatography (LC)-Orbitrap-full scan-high resolution mass spectrometry (HRMS).
It may be used as a reference standard for the analysis of 4,4′-methylene-bis(2-methylaniline) in dyes, cosmetics, finger paints and inks for pens and tattoos by LC-MS.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
