Application field
|
It is mainly used in the synthesis of medicine and agricultural chemical products, and is widely used in the fields of essence and fragrance, synthetic resin,cellulose,ink,paint,petroleum and electronic industry cleaning. In the agricultural chemical field, it is mainly used for the synthesis of (R)-(+)-2-(4-hydroxyphenoxyethanol) propionic acid (DHPPA), as an intermediate of herbicides such as Hushan, highly effective capillaria, Jing Stably killed, Jing Quaqualine and Oxynyl ester. This kind of herbicide is a typical representative of high efficacy, and the proportion of chiral pesticides is increasing. In recent years, due to its characteristics of high efficiency and low toxicity, wide herbicide spectrum, long application period, and safety for the following crops, it has been continuously developed and applied, and the market prospect is very broad.
