解説
…殺虫力はピレトリンI，IIがシネリン，ジャスモリンより強く，またノックダウン効果は，ピレトリンIがIIより強力である。また，ピレトリンをモデル化合物とした合成ピレスロイドの開発研究が盛んで，アレスリンやレスメスリンなどが開発された。また最近になって，酸部分をも改変したジフルベンズロン，フェノキシカルブ，ブプロフェジンなどのNRDC系やシクロプロパン環を含まないフェンバレラート，さらにはエステル構造を含まないエトフェンプロックスなどのきわめて強力な殺虫剤が開発され，従来主として衛生害虫の防除に利用されていたピレスロイドも農業用殺虫剤として注目されるようになった。…

使用
Allethrin is a synthetic pyrethroid derivative used as an insecticide. Allethrin is commonly used in many household insecticide products due to its low toxicity towards humans.
-
定義
Generic name for 2-allyl4-hydroxtcyclopenten-1-one ester of chrysanthemummonocarboxylic acid. A synthetic insecticide structurally similar to pyrethrin and used in the same manner. For other synthetic analogs, see barthrin, cyclethrin, ethythrin, furethrin. Pyrethrin I differs in having a 2,4-pentadienyl group in place of the allyl of allethrin.
-
一般的な説明
A clear amber-colored viscous liquid. Insoluble and denser than water. Toxic by ingestion, inhalation, and skin absorption. A synthetic household insecticide that kills flies, mosquitoes, garden insects, etc.
-
空気と水の反応
Insoluble in water.

反応プロフィール
Allethrin is an ester and ketone. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

健康ハザード
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
-
火災危険
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
-
农业用途
Insecticide: Allethrin is used almost exclusively to control flying and crawling insects in homes and industrial locations.
Used extensively in pet animal shampoos, to treat lice in
humans and in home and industrial sprays for flying insects, mosquitos, etc. It is available as mosquito coils,
mats, oil formulations and as an aerosol spray. It may be
hazardous to the environment; special attention should be
given to fish and honey bees. Not currently registered in the
U.S. Not approved for use in EU countries. Depending
on CAS registry number there are probably >100 global
suppliers.

接触アレルゲン
Pyrethroids, also called pyrethrinoids, are neurotoxic
synthetic compounds used as insecticides, with irritant
properties. Cypermethrin and fenvalerate have been
reported as causing positive allergic patch tests, but
only fenvalerate was relevant in an agricultural worker.
-
安全性プロファイル
Poison by intravenous, intracerebral, and intraperitoneal routes. Moderately toxic by ingestion and skin contact. An allergen. An insecticide. It can cause liver and kidney damage by all routes of entry into the body. Lung congestion may occur due to exposure. Local contact may cause contact dermatitis. Inhalation may cause asthma, coughing, wheezing, running nose and eyes. Mutation data reported. See also ALLYL COMPOUNDS and ESTERS. Slight fire hazard. When heated to decomposition it emits acrid fumes.

代謝経路
Allethrin was the first synthetic pyrethroid. Its stereochemistry is
RS(cyclopentenyl)lRcis-trans. It was further developed as bioallethrin
(RSlRtvuns) and then as S-bioallethrin (SlRtvuns), the most potent of the
three. All are very sensitive to light and are used almost entirely indoors.
Thus, there is only a limited amount of information on their environmental
fate published in the literature. Information on photodegradation
and on metabolism in insects and rodents has been reported.
