Beschreibung
Fenpropathrin is a pyrethroid, non-systemic acaricide and insecticide used to control many species of mite and other insects. It has a low aqueous solubility and is considered to be moderately volatile. It may be persistent in both soil systems and water bodies depending upon local conditions. Based on its physico-chemical properties there is a low risk of leaching to groundwater. Fenpropathrin is highly toxic to bees, fish and aquatic invertebrates and moderately toxic to bird, earthworms and algae. It is also moderately toxic to humans via the oral route. In information on chronic health effects have been identified.
Verwenden
Insecticide, acaricide.
Definition
ChEBI: A cyclopropanecarboxylate ester obtained by formal condensation between 2,2,3,3-tetramethylcyclopropanecarboxylic acid and cyano(3-phenoxyphenyl)methanol.
Vorbereitung Methode
Fenpropathrin is commercially produced through a multi-step chemical synthesis that involves esterification and cyclopropanation reactions. The process begins with the preparation of the alcohol intermediate, typically 3-phenoxybenzyl alcohol, which is then reacted with 2,2,3,3-tetramethylcyclopropane-1-carboxylic acid or its derivatives.
Allgemeine Beschreibung
Yellowish to brown liquid or solid, depending on purity and temperature. Used as an acaricide and insecticide.
Air & Water Reaktionen
In water, solubility is 14 ppm. Slowly oxidized in air. Decomposed by alkaline solutions.
Reaktivität anzeigen
A pyrethroid. Fenpropathrin is an ester and nitrile. 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. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids.
Mechanism of action
Non-systemic with contact and stomach action. Sodium channel modulator.
Pestizidtyp
Insecticide; Acaricide
