Preparation of 4,4′-diaminodiphenylmethane-(2H4) for use as internal standard in the quantification of 4,4′-diaminodiphenylmethane

A simple method has been developed for the synthesis of 4,4′‐diaminodiphenylmethane‐(2H4) for analytical purposes in gas chromatography‐negative ion chemical ionization mass spectrometry (GC‐NICIMS). It consists in a proton‐deuterium exchange reaction of the diamine using deutero‐hydrochloric acid i...
