Chemical compound

Etridiazole is a fungicide and pesticide used for prevention of pythium ultimum on cotton plants.[2]

Synthesis

Etridiazole can be synthesised from acetonitrile as follows:

It can also be is produced by the reaction of trichloroacetamidine hydrochloride with trichloromethanesulfenyl chloride, and then with sodium hydroxide in ethanol.[3]

Reactivity

Etridiazole is stable under normal conditions,[4] but degrades upon continuous exposure to sunlight,[5] and is hydrolysed by alkalis.[6] When heated to decomposition, it emits toxic fumes of hydrogen chloride, sulfur oxides, and nitrogen oxides.[7]

Safety

Etridiazole has been classified as a Group B2 Probable Human Carcinogen.[8]
