Kushandiswa
Diethylamino-sulfur trifluoride (DAST) chinhu chinoshandiswa zvakanyanya mukugadzira fluorination. Inhengo yemhuri ye (dialkylamino) sulfur trifluoride. DAST chinhu chinoshandiswa ne nucleophilic fluorination, chinogona kushandura boka realcohol hydroxyl kuita fluorine inoenderana uye aldehydes uye ketones kuita difluoride.
Zvakanakira
1.Kuchena kwakanyanya 95.0% min, Zvemukati zvakawanda.
2. Tine chitupa che ISO 9001, ISO14001, ISO22000
3.Anopfuura makore makumi maviri eruzivo rwekugadzira uye anopfuura makore gumi nemashanu eruzivo rwekutengesa kunze kwenyika.
4. Kutumirwa kwebatch diki uye kurongedza kunowanikwa
5. Tinogona kupa 10g-50g sampuro yemahara yebvunzo yako yerabhoritari.
kurongedza
1.1kg pabhodhoro
2.25kg padhiramu rimwe nerimwe
Kurongedza kunogonawo kugadziriswa zvichienderana nezvinodiwa nevatengi
Chengeta pa 2-8℃ Chengeta mumudziyo wakavharwa kure nechiedza. Dziviriro yenitrogen.
