Description

Pirimiphos Ethyl CAS NO 23505-41-1 is a synthetic organophosphate compound widely recognized for its potent insecticidal and acaricidal properties. This technical-grade active ingredient is critical for formulating effective crop protection solutions that safeguard agricultural yields. It is primarily required by agrochemical manufacturers and formulators serving the global agricultural sector.

Application

• As a key active ingredient in the formulation of broad-spectrum insecticide and acaricide products for agricultural use.
• For the control of a wide range of sucking and chewing pests on various crops, including stored grains.
• In the manufacturing of public health insecticides for vector control programs targeting mosquitoes and other disease-carrying insects.
• As an intermediate in the synthesis of other specialized organophosphate derivatives for research and development purposes.
• For use in non-crop applications, such as in animal housing or for the protection of materials, subject to local regulatory approvals.
