| Description | Diethylamine, also known as DEA or (C2H5)2nh, belongs to the class of organic compounds known as dialkylamines. These are organic compounds containing a dialkylamine group, characterized by two alkyl groups bonded to the amino nitrogen. It is a colorless liquid which often appears brown due to impurities. It is volatile and has a strong unpleasant odor. Diethylamine is an ammoniacal and fishy tasting compound. Diethylamine is found, on average, in the highest concentration within barley and apples. Diethylamine has also been detected, but not quantified, in a few different foods, such as common grapes, corns, and spinachs. This could make diethylamine a potential biomarker for the consumption of these foods. Diethylamine is a potentially toxic compound. It is miscible with water and ethanol. Diethylamine is a secondary amine with the molecular structure CH3CH2NHCH2CH3. It is a flammable, strongly alkaline liquid. |
