4-chloro-3-methyl-1,2-oxazol-5-amine - Introduction
Also known as Clomazone, is a pesticide and herbicide. It is a yellow to grayish yellow crystalline solid with a distinctive odor.
It is mainly used as a seedling control agent in farmland and orchards, and can be widely used in cotton, soybean, sugarcane, corn, peanuts and other crops. It inhibits the growth and development of weeds by inhibiting the activity of pigment synthase in target plants. It has a good control effect on broad-leaved weeds, but it is sensitive to some gramineous crops, so it is necessary to pay attention to choosing suitable grass fields and wide grass fields when using them.
The preparation method can be obtained by chlorination of 3-methylisoxazole-5-one. In the preparation process, the reaction temperature and pH value need to be controlled to ensure the purity and yield of the product.
When using and handling, you need to follow relevant safety measures. If you wear protective gloves, protective glasses and protective mask, avoid contact with skin and inhalation materials. At the same time, during storage and handling, avoid reactions with strong oxidants and strong acids to prevent the risk of fire and explosion. In the event of an accident or accidental ingestion, seek medical attention immediately and take the material packaging for disposal.
