티오파녹스 C화학적 특성, 용도, 생산
화학적 성질
Thiofanox is a colorless solid with a pungent odor.
용도
Thiofanox is a systemic soil insecticide used for the control of
aphids, mites, thrips, plant bugs, leafhoppers and beetles in/on sugar
beet and potatoes.
일반 설명
THIOFANOX is a colorless solid with a pungent odor. Used as a systemic insecticide and acaricide.
공기와 물의 반응
Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids.
반응 프로필
THIOFANOX is a thiocarbamate. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides.
건강위험
THIOFANOX is a carbamate pesticide. Carbamate pesticides are moderately to highly toxic. It is a cholinesterase inhibitor.
화재위험
(Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) Container may explode in heat of fire. When heated to decomposition, THIOFANOX emits very toxic fumes of nitrogen and sulfur oxides. Stable at normal storage temperature; reasonably stable to hydrolysis at less than 86F at pH 5-9.
Pharmacology
The insecticidal carbamates are cholinergic. Poisoned
insects and animals exhibit violent convulsions and
other neuromuscular disturbances. These insecticides
carbamylate acetylcholinesterase and may have a direct
action on acetylcholine receptors. The mechanism of interaction
with acetylcholinesterase is analogous to the normal
three-step hydrolysis of acetylcholine. However, the third
reaction step is much slower for the carbamylated enzyme
than for the acetylated one. The importance of structural
complementarity of the insecticidal carbamates to the
active site of acetylcholinesterase is demonstrated by the
pronounced difference in activities of D-2-(sec-butylphenyl)
methylcarbamate and L-2-(sec-butylphenyl) methylcarbamate
(the L isomer is five times more toxic) and of the 2-,
3-, and 4-substituted phenylmethylcarbamates, where the
4-isomers are virtually inactive.
Detoxification of carbamate insecticides occurs in vivo
through microsomal hydroxylation, N-demethylation of
carbamyl nitrogen, side chain oxidation, and ring hydroxylation.
Methylenedioxyphenyl synergists prevent oxidation
잠재적 노출
A potential danger to those involved in the manufacture, formulation and application of this thiocarbamate systemic insecticide and acaricide.
신진 대사 경로
The hydrolytic degradation and metabolism of thiofanox in soils, plants
and animals follow a common pathway. Oxidation of the S-methyl moiety
is the primary reaction to yield the thiofanox sulfoxide and sulfone.
Hydrolysis of the carbamate linkage to yield the oximes is only a minor
pathway for thiofanox and its oxidation products (Scheme 1).

비 호환성
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. Many materials in this group 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
폐기물 처리
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.
