Ethyl 4,4-difluoroacetoacetate - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| introduction | ethyl 4, 4-difluoroacetoacetate, also known as ethyl 4, 4-difluoro-3-oxobutyrate, boiling point 170.1 ℃(760mmHg), flash point 55.7 ℃, vapor pressure 1.49mmHg(25 ℃). In recent years, the application of difluoromethyl-containing compounds in medicine and pesticide creation has attracted extensive attention. Difluoromethyl can significantly enhance the physiological activity of organic molecular compounds than trifluoromethyl, and plays an important role in many biological organic molecules. |
| Uses | Ethyl 4, 4-difluoroacetoacetate is an important pesticide and pharmaceutical intermediate, which can be used to prepare fluazocycloamine (Sedaxane), benzoenfluoxazole (Solatenol,Benzovindiflupyr), pyrazonaphthylamine (Isopyrazam),, fluzolamide (Fluxapyroxad) and biphenopyramide (Bixafen). |
