A process for synthesis of fipronil |
| abstract |
The present disclosure relates to a process for the synthesis of Fipronil which is a broad spectrum insecticide (I). The process of the present disclosure provides fipronil with a yield in the range of 75% to 90% and purity in the range of 95% to 97%. By the process of the present disclosure, the amount of sulfone impurity i.e., 5-amino- 1 -(2, 6-dichloro-4-trifluoromethylphenyl)-3-cyano- 4-trifluoro methylsulfonyl pyrazole in fipronil observed is in the range of 0 % to 0.5 %. |
