N,N'-Diethylthiourea Chemical Properties,Uses,Production

Chemical Properties

white to buff-coloured solid


ChEBI: Thiourea in which each nitogen carries an ethyl substituent.

General Description

Buff solid or white powder.

Air & Water Reactions

N,N'-Diethylthiourea may be sensitive to exposure to air. . Slightly soluble in water.

Reactivity Profile

N,N'-Diethylthiourea is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition N,N'-Diethylthiourea emits toxic fumes.

Fire Hazard

Flash point data are not available for N,N'-Diethylthiourea, but N,N'-Diethylthiourea is probably combustible.

Contact allergens

Diethylthiourea, a thiourea derivative, is used mainly as a rubber chemical, particularly in solid neoprene products.

Safety Profile

Poison by ingestion. Moderately toxic by intraperitoneal route. Questionable carcinogen with experimental carcinogenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and SOx

Purification Methods

Crystallise it from *benzene. [Beilstein 4 H 118, 4 I 355, 4 II 610, 4 III 220, 4 IV 375.]
