Allylthiourea Chemical Properties,Uses,Production

Chemical Properties

white crystals or powder


chelating agent


ChEBI: A thiourea with a prop-2-enyl group attached to one of the amines.

General Description

White crystalline solid with a slight garlic odor.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Allylthiourea may react vigorously with strong oxidizing agents. Can react exothermically with reducing agents (such as alkali metals and hydrides) to release gaseous hydrogen. May react exothermically with both acids and bases. May generate flammable gases in combination with aldehydes, nitrides, and hydrides. Incompatible with peroxides and acid halides.

Health Hazard

SYMPTOMS: Contact eczema due to sensitization in humans has been reported.

Fire Hazard

Flash point data are not available for Allylthiourea, but Allylthiourea is probably combustible.

Purification Methods

Recrystallise it from H2O. It is soluble in 30 parts of cold H2O, and it is soluble in EtOH but insoluble in *C6H6. It has also been recrystallised from acetone, EtOH or ethyl acetate, after decolorising with charcoal. The white crystals have a bitter taste with a slight garlic odour and are TOXIC. An unstable crystalline form is obtained by recrystallising from the melt. [McCrone et al. Anal Chem 21 421 1949, Beilstein 4 IV 1072.]
