Early Growth Response-3 - Preparation Method
Open Data Verified Data
from 4-chloro-2-nitroaniline in benzene or toluene solvent, in the presence of pyridine catalyst reaction with diketene, to produce the corresponding open acetylation, the product is treated with an aqueous alkaline solution to form the corresponding quinoxalinone nitrogen oxide. Quinoxalinone nitrogen oxide in the presence of sodium hydroxide (or potassium hydroxide), toluene water as solvent, reaction at 60~70 deg C, the formation of ammonia oxide in aqueous alkali solution, at room temperature, with a certain amount of sodium borohydride reaction, get 6 chlorine 2 (1H)-quinoxalinone. 6 A chlorine 2 (1H)-quinoxalinone in DMF solution with thionyl chloride, 2,6-= chloroquinoxaline. 2,6-= chloroquinoxaline is then condensed with hydroquinone in DMF under nitrogen to give 4-(6-chloro-2-quinoxalinyloxy) phenol. 4-(-6-chloro -2-quinoxalinoxy) phenol and a-halogenated propionic acid ethyl ester in acetonitrile solution, with potassium carbonate as acid binding agent, condensation to obtain quetiapine. Quetiapine can also be prepared by direct action of 2,6-= chloroquinoxaline and ethyl p-hydroxyphenoxypropionate in the presence of potassium carbonate in an acetonitrile solution under reflux.

Early Growth Response-3 - Use
Open Data Verified Data
as a post-emergence herbicide, annual and perennial weeds can be selectively controlled. It has excellent herbicidal activity on gramineous weeds, and is highly selective between gramineous weeds and dicotyledonous crops. The stems and leaves can complete the absorption of the chemicals in a few hours, and the annual weeds can spread throughout the whole plant in 24 hours. Suitable for cotton, soybean, rape, peanut, flax, apple, grape, sugar beet and a variety of wide leaf vegetable crops, control of monocotyledonous weeds, dog tooth root, perennial weeds such as reeds also have a role. In the mixed field of single-and double-leaf weeds, it can be used together with the herbicides for controlling broad-leaved weeds such as sugarbeet tannin, Huwei, broad-leaved litter and weed burning.
