Usage

General Description

Difenoxuron is a chemical compound that belongs to the group of urea derivatives. It is commonly used as an insecticide to control pests in agricultural crops and stored commodities. Difenoxuron works by disrupting the normal growth and development of insect larvae, leading to their eventual paralysis and death. It is effective against a wide range of insects, including beetles, moths, and caterpillars. However, due to its potential environmental and health risks, its use is regulated in many countries. Difenoxuron is considered to be moderately toxic to mammals and has been found to persist in the environment for an extended period, making it a cause for concern in terms of its potential impact on non-target organisms and ecosystems.

Synthesis method of phenylurea herbicide or deuteration-labeled phenylurea herbicide

The invention relates to a synthesis method of a phenylurea herbicide or a deuteration-labeled phenylurea herbicide (a compound of a formula (I)). The compound of the formula (I) is obtained by reacting a compound of a formula (II) with a dimethylamine salt or D6-dimethylamine salt in the presence of an organic base. According to the synthesis method, the side reaction of substituted phenyl isocyanate and water or alcohol is avoided, the leakage of dimethylamine or dimethylamine-D6 is reduced, and the synthesis method has the advantages of simple operation, low requirements for equipment, low cost, high yield, and fewer by-products. The formula I is shown in the description.
