Safety Information
N,N'-Diethylthiourea Usage And Synthesis
  • DescriptionDiethylthiourea, a thiourea derivative, is used mainly as a rubber chemical, particularly in solid neoprene products.
  • Chemical Propertieswhite to buff-coloured solid
  • UsesDiethyl thiourea is the inhibitor of corrosion in metal pick/ing solutions; accelerator for mercaptan-modified chloroprene rubber; antidegradant for natural, nitrile-butadiene, styrene-butadiene, and chloroprene rubbers
  • DefinitionChEBI: Thiourea in which each nitogen carries an ethyl substituent.
  • General DescriptionBuff solid or white powder.
  • Air & Water ReactionsN,N'-Diethylthiourea may be sensitive to exposure to air. . Slightly soluble in water.
  • Reactivity ProfileN,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 HazardACUTE/CHRONIC HAZARDS: When heated to decomposition N,N'-Diethylthiourea emits toxic fumes.
  • Fire HazardFlash point data are not available for N,N'-Diethylthiourea, but N,N'-Diethylthiourea is probably combustible.
  • Contact allergensDiethylthiourea, a thiourea derivative, is used mainly as a rubber chemical, particularly in solid neoprene products.
  • Safety ProfilePoison 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 MethodsCrystallise it from *benzene. [Beilstein 4 H 118, 4 I 355, 4 II 610, 4 III 220, 4 IV 375.]
