• Description: 5-Chlorovaleryl chloride 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 herbicidal activity, high selectivity, extremely low mammalian toxicity and good environmental characteristics, and have become a hot spot in the research and development of herbicides in the world in recent years.
• Uses: 5-Chlorovaleroyl chloride (5-CVC) has been used in the development and validation of a GC-FID method for the analysis of low level impurities present in 5-CVC. It has been used in the synthesis of anion-exchange resins by acylation of polystyrene/divinylbenzene and subsequent amination with trimethylamine. It is commonly used as alkylating agent in the synthesis of pharmaceutical intermediates and other specialty chemicals. 5-Chlorovaleroyl chloride (5-CVC) has been used in the development and validation of a GC-FID method for the analysis of low level impurities present in 5-CVC.
