Ukusetyenziswa

I-Diethylamino-sulfur trifluoride (DAST) sisixhobo esisetyenziswa kakhulu kwi-fluorination reagent kwi-organic synthesis. Silungu losapho lwe-(dialkylamino) sulfur trifluoride. I-DAST sisixhobo esisetyenziswa kakhulu kwi-fluorination reagent, esinokuguqula iqela le-alcohol hydroxyl libe yi-fluorine ehambelanayo kunye ne-aldehydes kunye nee-ketones zibe yi-difluoride.

Inzuzo

1. Ubumsulwa obuphezulu 95.0% min, Umxholo ophezulu.
