Fenpropathrin Usage And Synthesis

Uses

Insecticide, acaricide.

Definition

ChEBI: A cyclopropanecarboxylate ester obtained by formal condensation between 2,2,3,3-tetramethylcyclopropanecarboxylic acid and cyano(3-phenoxyphenyl)methanol.

General Description

Yellowish to brown liquid or solid, depending on purity and temperature. Used as an acaricide and insecticide.

Air & Water Reactions

In water, solubility is 14 ppm. Slowly oxidized in air. Decomposed by alkaline solutions.

Reactivity Profile

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.
