説明
Pyridaphenthion is a pale yellow solid, mp 54.5–56 ?C,
vp 0.00147 mPa (20 ?C). Solubility in water is 100 mg/L
(20 ?C). It is very soluble in acetone, methanol, and diethyl
ether. Log Kow = 3.2.
使用
Pyridaphenthion is used to control a wide range of chewing and
sucking insects and mites in rice, vegetables, fruit and ornamentals.
安全性プロファイル
Poison by intraperitoneal route. Moderately toxic by ingestion and skin contact. When heated to decomposition it emits very toxic fumes of SOx, POx, and NOx. Used to control chewing and suckmg insects on rice, fruits, vegetables, and cereals.
代謝経路
Pyridaphentluon is photolytically transformed into the oxon and phenylmaleic
hydrazide. In the mouse its metabolism involves oxidative
dearylation, oxidative desulfuration to the oxon, de-ethylation and conjugation
of phenylmaleic hydrazide produced as the ultimate product of
stage I metabolism and is typical of many phosphorothioates. A marked
difference between metabolism in mice and rats was shown, with rats
excreting no desethylpyridaphenthion and excreting all of the phenyl-maleic
hydrazide in an unconjugated form.
代謝
More than 70% of the dose
administered to rats and mice was excreted within 24 h
in the urine. The major metabolites excreted are phenylmaleic
hydrazide and desethyl pyridafenthion-oxon. The
half-life in soil is 11–24 d.
