4-(Dimethylamino)butyronitrile Chemical Properties,Usage,Production

Uses

4-(Dimethylamino)benzonitrile(DMABN) can be used in the synthesis of 3,6-diphenyl-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione derivatives. DMABN is also used in photophysical studies due to its ability to undergo intramolecular charge transfer (ICT) from the dimethylamino moiety to the cyanophenyl moiety on photo-excitation leading to the appearance of dual fluorescence.
