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 in the production of LSD and therefore it is strictly monitored in the United States by the Drug Enforcement Administration (DEA).
