5-Chlorovaleryl chloride CAS 1575-61-7 is an important synthetic intermediate of pyrazole herbicides. 5-Chloropentanoyl chloride is used as the raw material of 1,1,7-trichloro-1-hepten-3-one, and then the third-generation pyrazole herbicides can be synthesized. Pyrazole herbicides have the characteristics of ultra-efficient chemical activity, high selectivity, extremely low mammalian toxicity and good environmental characteristics, etc., and have become the hot spot of herbicide research and development in the world in recent years. As the demand for high-efficiency herbicides continues to expand, so does the demand for 5-chlorovaleryl chloride as an intermediate.
