说明

4,4'-二氨基二苯基甲烷 (MDA) 是一种芳香族二胺,在工业上用作制造聚氨酯产品、异氰酸酯、多异氰酸酯等的前体。它还用作环氧树脂和弹性体生产中的硬化剂。
4,4'-二氨基二苯基甲烷是环氧树脂的固化剂。 由甲醛苯胺与盐酸苯胺和苯胺加热制得。

一般描述

4,4′-Diaminodiphenylmethane (MDA) is an aromatic diamine, which finds industrial applications as a precursor in the manufacturing of polyurethane products, isocyanates, polyisocyanates, etc. It is also used as a hardener in the production of epoxy resins and elastomers.
4,4′-Diaminodiphenylmethane is a curing agent for epoxy resins. It is prepared from formaldehyde aniline when heated with aniline hydrochloride and aniline.
 

应用

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
4,4′-Diaminodiphenylmethane is used as an analytical reference standard for the quantification of the analyte in the following:
  • Urine samples using gas-chromatography coupled to mass spectrometry (GC-MS).
  • Hepatic microsomal incubation mixture from rabbits using high-performance liquid chromatography-plasma spray mass spectrometry (HPLC-PSP-MS), offline HPLC with fast atom bombardment mass spectrometry (FAB-MS) and fast atom bombardment tandem mass spectrometry (FAB-MS/MS).

It is reported to be used in the synthesis of amino modified multi-walled carbon nanotubes/polydimethylsiloxane, which serves as a coating for the stir bar sorptive extraction (SBSE) of phenols in environmental samples, followed by analysis using high performance liquid chromatography with ultraviolet detection (HPLC-UV).
