TRIMETHYLTHIOUREA(Cas 2489-77-2) Usage

Air & Water Reactions

Very slightly soluble in water.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition TRIMETHYLTHIOUREA emits toxic fumes of nitrogen oxides and sulfur oxides.

Fire Hazard

Flash point data for TRIMETHYLTHIOUREA are not available; however, TRIMETHYLTHIOUREA is probably combustible.

Contact allergens

Trimethylthiourea is a thiourea derivative used, for example, for polychloroprene (neoprene) rubber vul- canization. Patients sensitized to ethylbutyl thiourea can also react to trimethylthiourea.

Safety Profile

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

General Description

Prisms (from benzene or ligroin) or off-white powder.
