Permethrinic acid methyl ester

Description:

Permethrinic acid methyl ester, with the CAS number 61898-95-1, is an ester derivative of permethrin, a widely used synthetic pyrethroid insecticide. This compound exhibits characteristics typical of pyrethroids, including high efficacy against a broad spectrum of pests and low toxicity to mammals and birds. It is generally stable under various environmental conditions, making it suitable for agricultural applications. The chemical structure features a methyl ester functional group, which contributes to its solubility in organic solvents and enhances its bioavailability. Permethrinic acid methyl ester is often utilized in formulations for pest control in agricultural settings, as well as in household insecticides. Its mode of action involves disrupting the nervous system of insects, leading to paralysis and death. Additionally, it is important to consider its environmental impact, as it can be toxic to aquatic organisms and beneficial insects. Proper handling and application are essential to minimize risks associated with its use.

Methyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate

CAS: 61898-95-1

Methyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate is a pyrethroid insecticide. It is formulated as an emulsifiable concentrate and applied to the soil surface or injected into the root zone of plants. This insecticide is also used in combination with other pesticides to provide broad spectrum control of insect pests. Methyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate is chemically synthesized from 2,3-dihydro-1,3-benzodioxole and chloroacetic acid. The mechanism of action for this pesticide is not well understood but may be due to its ability to inhibit hydrolase enzymes. This product also has a low toxicity on mammals and birds that are exposed orally or through inhalation at high concentrations.
