Product Description

Introduction	Fipronil (Fipronil), chemical name 5-amino -1-(2,6 dichloro-4-trifluorotolyl)-4-Trifluoromethyl-sulfinyl pyrazole -3-nitrile, is the first benzyrazole used for pest control. Since its discovery in 1987, it has been widely used in many fields such as agriculture and veterinary medicine, and has become an important pesticide variety. Fepperoni, the trade name is Ruijin, is a new type of benzyrazole insecticide, which is compared with traditional insecticides (organophosphorus, pyrethroids, carbamates), It has the advantages of broad spectrum and high efficiency. It has been widely used in many agricultural fields and is a commonly used insecticide for pest control.
pharmacological effects	fipronil mainly induces Cl-flow by blocking the Cl-channel of the nerve membrane controlled by γ-aminobutyric acid receptor, causing extreme excitement of the nervous system and leading to death of worms, thus achieving the prevention and control effect on various economic pests.
Preparation	4-trifluoromethylaniline reacts with hydrochloric acid in hydrogen peroxide to generate 2,6-dichloro-4-trifluoromethylaniline; it is diazotized with sodium nitrite and hydrochloric acid to form diazonium salt, and is condensed with ethyl 2, 3-dicyanopropionate to form a condensate, and a pyrazole ring is formed in a closed loop in ammonia; then it is condensed with trichloromethyl sulfinyl chloride, the reaction product of perchloromethyl mercaptan oxidation by hydrogen peroxide, to obtain sulfide, and then undergo a replacement reaction with hydrogen fluoride to obtain non-prednis. The chemical reaction formula is as follows:
toxicity	acute oral LD50 in rats is 100 mg/kg, and acute percutaneous LD50 in rats is> 2000 mg/kg. Acute inhalation of LC50 in rats was 0.682mg/L. No irritation to rabbit skin, no irritation to eye mucosa. Ames test was negative and had no teratogenic effect. The LC50 of carp is 0.34mg/L (96h), and the oral LD50 of wild ducks is> 2150mg/kg.
Uses	Fluoropyrazole-containing broad-spectrum insecticides have high activity and wide application range. They are very sensitive to Hemiptera, Thysanoptera, Coleoptera, Lepidoptera and other pests, as well as pyrethroid and carbamate insecticides. It can be used for rice, cotton, vegetables, soybeans, rape, tobacco leaves, potatoes, tea, sorghum, corn, fruit trees, forests, public health, animal husbandry, etc., to control rice borers, brown planthoppers, rice weevil, cotton bollworm, armyworm, Plutella xylostella, Cabbage worm, Cabbage armyworm, armyworm, beetle, caterpillar, fruit tree mosquito, wheat aphid, coccidia, trichomonas, etc. The recommended dosage is 12.5~150g/hm2. China has approved field efficacy tests on rice and vegetables. The preparation is 5% gum suspension and 0.3% granules. Mainly used in rice, sugar cane, potatoes and other crops, animal health is mainly used to kill parasites such as fleas and lice on cats and dogs
production method	preparation of 5-amino -3-cyano -1-(2, 6-dichloro-4-trifluoromethyl phenyl) pyrazole suspension prepared from 7g sodium nitrite and 27.5mL concentrated sulfuric acid is diluted with acetic acid, and 21.2 g2 is added dropwise at 25~32 ℃, the acetic acid solution of 6-dichloro -4-trifluoromethylaniline is 50mL, the temperature is raised to 55 ℃, the temperature is heated for 20min, the solution of acetic acid (60mL) and water (125mL) of ethyl 2,3-dicyanopropionate is poured into, after stirring for 15min, water is added, the oil layer is separated, the dichloroethane is extracted, the oil layer is merged, the ammonia water is washed to pH 9, stratified, washed with water and dilute hydrochloric acid, dried, filtered and evaporated, the oil was recrystallized in toluene and hexane with 70.9% yield. Preparation of 5-Amino-3-cyano-1-(2, 6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylthiopyrazole A dichloromethane solution of trifluoromethyl sulfide (10.8g) was added dropwise to a methylene chloride solution containing 20g of the preceding product within 1h. Stir overnight at room temperature, wash, dry, filter, desolvate to obtain 26.3g of solid, recrystallize to obtain the product with 92% yield. Under the stirring of the synthesis of fipronil, the dichloromethane solution of 10g of the previous product was treated with 4.5g m-chloroperoxybenzoic acid. After stirring overnight, 2 parts of 1.6g m-chloroperoxybenzoic acid were added and placed for 2 days. Diluted with ethyl acetate, washed with sodium sulfite solution, sodium carbonate solution and water in turn, dried, filtered, desoluted, eluted and purified with dichloromethane on SiO2 chromatographic column to obtain fipronil 6.0g with 57.8% yield. Please refer to the synthesis of a new insecticidal type-fipronil, Issue 3 of Pesticide Magazine 2002.
