    Ukusetshenziswa

    I-Diethylamino-sulfur trifluoride (DAST) iyi-reagent ye-fluorination esetshenziswa kabanzi ekuhlanganisweni kwezinto eziphilayo. Iyilungu lomndeni we-(dialkylamino) sulfur trifluoride. I-DAST iyi-reagent ye-fluorination ye-nucleophilic, engaguqula iqembu le-alcohol hydroxyl libe yi-fluorine ehambisanayo kanye nama-aldehydes nama-ketone abe yi-difluoride.

    Inzuzo

    1. Ubumsulwa obuphezulu 95.0% min, Okuqukethwe okuphezulu.
    2. Sinesitifiketi se-ISO 9001, ISO14001, ISO22000
    3.Iminyaka engaphezu kwengu-20 yesipiliyoni sokukhiqiza kanye neminyaka engaphezu kwengu-15 yesipiliyoni sokuthengisa kwamanye amazwe.
    4. Ukuthunyelwa kwe-batch encane kanye nokupakishwa okungaphansi kuyatholakala
    5. Singanikeza isampula yamahhala engu-10g-50g yokuhlolwa kwakho kwelebhu.

    ukupakisha

    1.1kg ngebhodlela
    2.25kg ngesigubhu ngasinye
    Ukupakisha nakho kungenziwa ngezifiso ngokwezidingo zamakhasimende
    2-methylpyrazineo0m

    Izimo zokugcina

    Gcina ku-2-8℃ Gcina esitsheni esivaliwe kude nokukhanya. Ukuvikelwa kwe-nitrogen.
