Uses

Used in Agricultural Industry:
Difenoxuron is used as an insecticide for controlling a broad spectrum of pests such as beetles, moths, and caterpillars in agricultural crops. Its application helps protect crops from damage and contributes to maintaining yield and quality.
Used in Stored Commodities Protection:
In addition to its agricultural applications, Difenoxuron is also utilized for the protection of stored commodities. It serves to prevent infestation and damage by insects during storage, ensuring the preservation of goods.
However, due to its potential environmental and health risks, the use of Difenoxuron is regulated in many countries. It is considered to be moderately toxic to mammals and has been found to persist in the environment, which raises concerns about its 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.
