Diethylamine is a secondary amine with the molecular structure CH3CH2NHCH2CH3 (also written as C4H11N). It is a flammable, weakly alkaline liquid. It is miscible with water and ethanol. It is a colorless liquid which often appears brown due to impurities. It is volatile and has a strong unpleasant odor.

Diethylamine is manufactured from ethanol and ammonia and is obtained together with ethylamine and triethylamine. It is used as a corrosion inhibitor and in the production of rubber, resins, dyes and pharmaceuticals.

Diethylamine is a corrosive chemical and contact with skin may cause irritation or burns.

Diethylamine can be used to produce LSD and is strictly watched by the DEA.
