Quinalphos is a chemical compound from the group of organophosphates and thiophosphoric acid esters and an insecticide introduced by Bayer AG (now Bayer CropScience ) in 1969 .

Extraction and presentation

Quinalphos can be obtained by reacting o -phenylenediamine with dichloroacetic acid and then with DEPCT .

properties

Quinalphos is a flammable colorless solid that is practically insoluble in water. It hydrolyzes easily, except in slightly basic conditions.

use

Quinalphos is used as an insecticide on a number of crops against biting and sucking pests. The methyl form (quinalphos-methyl, CAS number: 13593-08-3) is also used as a pesticide.

Admission

In the European Union, quinalphos is not included in the list of permitted active ingredients in pesticides. In Germany, Austria and Switzerland, no pesticides with this active ingredient are permitted.
