使用
Thiophanate-Methyl is a systematic fungicide of the thiophanate class. Thiophanate-Methyl is commonly used in agriculture to protect against powdery mildew, rot and other fungal diseases in fruits, ve
getables and other crops.
定義
ChEBI: A member of the class of thioureas that is the dimethyl ester of (1,2-phenylenedicarbamothioyl)biscarbamic acid. A fungicide effective against a broad spectrum of diseases in fruit, vegetables, turf and other crops including eyespot, scab, powdery mildew a
d grey mould.
一般的な説明
Colorless crystals or light brown powder.
空気と水の反応
Insoluble in water.
反応プロフィール
Thiophanate-methyl is incompatible with strong acids and bases, and with strong reducing agents such as hydrides. Produces flammable gaseous hydrogen with active metals or nitrides. Incompatible with strong oxidizing acids, peroxides. Incompatible with alkaline material. Forms complexes with copper salts .

職業ばく露
Methyl thiophanate is thiocarbamate ester, used in the synthesis of polymers and in agriculture as pesticides, soil fumigants, and seed disinfectants.
発がん性
Those long-term studies evaluated a
variety of toxicity end points including carcinogenicity.
Both benomyl and carbendazim were weak carcinogens in
some in vivo studies. Rats of the SpDxAug strain were fed 80,
400, and 2000 ppm for 2 years and no evidence for an
increase in tumors was seen. In carcinogenicity
studies in mice with carbendazim, similar liver tumor finding
were found in CD-1 or Swiss strains. On the other
hand, no evidence of tumors was seen in a similar study
conducted using the NMRKf mouse strain, a strain that has a
low incidence of spontaneous tumors.
代謝経路
Thiophanate methyl degradation in water (hydrolytic/ photolysis), soils,
plants and animals follows a common pathway that involves the initial
conversion into methyl benzimidazol-2-ylcarbamate (carbendazim).
Prior to benzimidazole ring formation, at least one side chain undergoes
an oxidative desulfuration reaction and partial hydrolysis (even to
the substituted aniline). Once formed, carbendazim is degraded primarily
via an oxidative mechanism (in animals) or through hydrolysis
to 2-aminobenzimidazole (in soils). Possible metabolism pathways of
thiophanate methyl are depicted in Scheme 1.

不和合性
Thiocarbamate esters are combustible; dust may form explosive mixture with air. Decomposes163℃Thiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of thiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine. Thio and dithio carbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of thiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates are incompatible with acids, peroxides, and acid halides.
廃棄物の処理
In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
