Acrinathrin is a chemical compound from the group of pyrethroid esters.

Production and representation

Acrinathrin can be obtained by a multi-step reaction starting from 2 -trifluoro- 1- trifluormethylethyldichloracetat with triphenylphosphine, ammonia, chrysanthemic acid, ozone, and m- Phenoxycyanobenzylalkohol.

Properties

Acrinathrin is a white to pale yellow solid which is practically insoluble in water. Its chemical structure is similar to cypermethrin, wherein the chlorine atoms are replaced by a poly-fluorinated ester group. The compound was discovered in the 1980s by Roussel Uclaf and first synthesized. It is stable under acidic conditions, but unstable under diffuse light and alkaline conditions.

Use

Acrinathrin is used as an insecticide and acaricide against a number of herbivorous mites. In the EU, the application has been approved as an insecticide and acaricide in quantities not exceeding 22.5 g / ha per application on 1 January 2012. For so far available on the market plant protection products containing acrinathrin and do not meet the requirements, the approval is necessary, no later than December 31, 2015 amended or revoked.

In Germany, Austria and Switzerland, no plant protection products containing this active ingredient are allowed.
