2,4-Difluoroaniline

CAS367-25-9

Litšobotsi tsa lik'hemik'hale: motsoako o mosehla o bobebe o nang le oli.

Tšebeliso: 2,4-Difluoroaniline ke sehlahiswa se mahareng ho qaptjweng ha dintho tse phelang. Merianeng, e sebediswa ho qaptjweng ha difluorophenylsalicylic acid le polyfluorodiphenyl acid. Difluorophenylsalicylic acid ke sehlahiswa se seng sa anti-inflammatory se seng sa carboxylic acid (NSAID), se nang le lebitso la machaba le seng la beng ba sona (INN) Diflunisal. Sehlahiswa sena se setjha sa salicylic acid, le hoja se se na sehlopha sa acetyl sa aspirin, se na le sehlopha sa difluorophenyl, se fellang ka ditlamorao tse fokolang tsa antiplatelet, dikarabelo tse bobebe tsa mala, le nako ya tshebetso e nkang dihora tse 8-12. E kanna ya ba sehlahiswa se tshepisang ka ho fetisisa sa salicylic acid. Hape ke sehlahiswa sa bohlokwa tlhahisong ya dibolayadikokwanyana.
