N,N'-Dimethylethylenediamine (DMEDA) is the
organic compound
Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-co ...
with the formula (CHNH)CH. It is a colorless liquid with a fishy odor. It features two secondary amine functional groups. Regarding its name, N and N' indicate that the methyl groups are attached to different nitrogen atoms.
