N,N'-DICYCLOHEXYLTHIOUREA(1212-29-9) 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). This compound is incompatible with acids and oxidizing agents. N,N'-DICYCLOHEXYLTHIOUREA(1212-29-9) reacts with water.

This chemical may be sensitive to prolonged exposure to air. Insoluble in water.

ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits very toxic fumes.

Flash point data for this chemical are not available. N,N'-DICYCLOHEXYLTHIOUREA is probably combustible.

1,3-Dicyclohexylthiourea is used in the evaluation of its sensitivity, specificity and relative predictivity of battery of three in vitro genotoxicity tests to discriminate rodent carcinogens and non-carcinogens.
