Английская Википедия:Ethylene thiourea
Шаблон:Chembox Ethylene thiourea (ETU) is an organosulfur compound with the formula Шаблон:Chem2. It is an example of an N,N-disubstituted thiourea. It is a white solid. It is synthesized by treating ethylenediamine with carbon disulfide.[1]
Ethylene thioureas are an excellent accelerant of vulcanization of neoprene rubbers. In commercial use is the N,N'-diphenylethylenethiourea. Due to reproductive toxicity, carcinogenicity, and mutagenicity, alternatives are being sought to the ethylenethioureas. One candidate replacement is N-methyl-2-thiazolidinethione.[2]
Ethylene thiourea can be used as a biomarker of exposure to ethylenebisdithiocarbamates (EBDTCs), which are frequently employed as fungicides in agriculture, mainly on fruits, vegetables and ornamental plants.[3]
EPA classification
EPA (United States Environmental Protection Agency) has classified ethylene thiourea as a Group B2, probable human carcinogen.[4] Ethylene thiourea has been shown to be a potent teratogen (causes birth defects) in rats orally or dermally exposed.
