Usage

Uses

Used in Agricultural Industry:
CHLORFENVINPHOS is used as an insecticide for controlling a wide range of pest insects in agricultural settings. Its application is aimed at protecting crops from damage caused by these pests, thereby ensuring crop yield and quality.
However, due to its high toxicity and potential for causing harm, the use of CHLORFENVINPHOS has been restricted or banned in some countries. This is to mitigate the risks associated with its exposure to humans, animals, and the environment. Despite these restrictions, it remains in use in certain parts of the world, highlighting the ongoing debate and concern regarding its potential negative impact on human and environmental health.

Preparation of carbon-14 labeled organophosphate pesticides: Chlorfenvinphos

Synthesis of [vinyl-14C]chlorfenvinphos, utilizing [14C]iodomethane as the source of the label, was accomplished in 28% radiochemical yield by the methylation of 2,4-dichlorobenzoyl chloride, chlorination of the resulting [14C]-2,4-dichloroacetophenone, and condensation of the product with triethylphosphite. The product, isolated as a mixture of E and Z isomere (3.6 and 96.3%, respectively), was obtained in >99% purity and had specific activity 20 mCl/mmol.
