4,4'-DIAMINO-3,3'-DIMETHYLDIPHENYLMETHANE Chemical Properties,Uses,Production

Chemical Properties

White powder. Soluble in ethanol and hot water.

Uses

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.

Uses

4,4'-Diamino-3,3'-dimethyldiphenylmethane can be used for preparation polyimide and epoxy resin material.

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.

Safety Profile

Confirmed carcinogen with experimental carcinogenic data. Moderately toxic by ingestion. An eye irritant. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
