CYANOPHOS

Описание

Cyanophos is an amber liquid, decomposes at 119–120 ?C, vp 105 mPa (20 ?C). Solubility in water is 46 mg/L (30 ?C). It is soluble in most organic solvents. Log Kow = 2.65. Cyanophos is effective in controlling a variety of insect pests including rice stem borers. Major formulation types are dustable powder, emulsifiable concentrate, wettable powder, and ultra low volume liquid.

Химические свойства

Cyanophos is a yellow to reddish-yellow or amber liquid.

Использование

Cyanophos is used to control a number of chewing and sucking pests in cotton, fruit and vegetables and public health pests.

Общее описание

Yellow to reddish-yellow transparent liquid. Used as an insecticide against rice stem borers and house flies. Not registered as a pesticide in the U.S.

Профиль реактивности

Organophosphates, such as CYANOPHOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Угроза здоровью

CYANOPHOS is an organophosphorus insecticide. It is a cholinesterase inhibitor. Death may occur after a massive oral dose; with smaller accidental doses, onset of illness may be delayed.

Пожароопасность

(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Unstable. Rapidly decomposes under alkaline conditions and upon exposure to light.

Возможный контакт

A potential danger to those involved in the manufacture, formulation, and application of this insecticide which is used against rice stem borers and house flies. It is not registered as a pesticide in the United States. Incompatibilities: Alkaline materials and exposure to light can cause rapid decomposition. Contact with oxidizers may cause the release of phosphorous oxides. Contact with strong reducing agents, such as hydrides, may cause the formation of flammable and toxic phosphine gas.

Метаболический путь

The metabolism of cyanophos in plants and mammals is similar with deactivation via demethylation to desmethylcyanophos being important routes in both systems. Activation via oxidative desulfuration to cyanophos oxon, which is itself demethylated, also occurs in both plants and mammals. 4-Cyanophenol is an important metabolite which probably occurs principally by hydrolysis of the oxon in plants but in mammals is produced by oxidative dearylation of cyanophos also. In mammals it is conjugated as the sulfate ester as a major liver and urinary metabolite but conjugates of 4-cyanophenol have not been reported in plants.

Метаболизм

The main biodegradation pathways in mammals are demethylation and aryl ester bond cleavage; the liberated cyanophenol is excreted in the form of the sulfate ester, formed by conjugation. The metabolism in plants is similar to that in mammals except the cyanophenol conjugation.
