I-Diethylaminosulfur Trifluoride (DAST, CAS 38078-09-0) – Umenzi noMboneleli Ophambili waseTshayina

Intshayelelo

I-Diethylaminosulfur Trifluoride (DAST, CAS No. 38078-09-0) yi-reagent ekhethekileyo ye-fluorinating esetyenziswa kakhulu kwi-pharmaceuticals, agrochemicals, kunye ne-organic synthesis. Njengomvelisi kunye nomthengisi omkhulu we-DAST eTshayina, sinikezela nge-DAST ecocekileyo kakhulu ngolawulo oluqinileyo lomgangatho, siqinisekisa ukusebenza okuphezulu kwizicelo zoshishino kunye nophando.

Iimpawu zeMveliso

• Ifomula yeKhemikhali: (C₂H₅)₂NSF₃

• Inombolo ye-CAS: 38078-09-0

• Ubunyulu: ≥98% (HPLC)

• Inkangeleko: Ulwelo olungenambala ukuya kolutyheli olukhanyayo

• Indawo yokugcina izinto: Ifuna -20--2°C efrijiniukuthintela ukubola

• Uzinzo: Inokufuma kakhulu; kufuneka iphathwe ngegesi engangenisi mandla (N₂/Ar)

Usetyenziso lwe-DAST

I-DAST yi-reagent eguquguqukayo enendima ebalulekileyo kwi:

1. Amayeza: Ukunyibilika kwezinto ezidityaniswe namayeza (umz., ii-steroids, ii-antiviral compounds).

2. Iikhemikhali zezolimo: Ukwenziwa kwezibulali-zinambuzane kunye nezibulali-zinambuzane ezine-fluorine.

3. Ukwenziwa kwezinto eziphilayo: Ukutshintshatshintsha kwee-alcohols, ii-carbonyls, kunye nee-heterocycles ngokukhetha.

4. Isayensi yezixhobo: Ukuveliswa kwee-fluoropolymers kunye neekristale zolwelo.

Kutheni Ukhetha i-DAST Yethu?

1. Umgangatho kunye nobunyulu obungenakuthelekiswa nanto

• I-DAST yethu ivavanywa ngokuqatha yi-HPLC/GC-MS ukuqinisekisa ubunyulu obuyi-≥98%, nto leyo enciphisa iimpembelelo ezingalindelekanga.

• Ukuhambelana kweqela ngalinye ukuze kusebenze ngokuthembekileyo.

2. Amandla okuvelisa aPhambili

• Eyona ndawo inkulu yokuvelisa i-DAST eTshayina eneenkqubo eziqinisekisiweyo ze-ISO 9001.

• Imveliso yonyaka yeetoni ezingama-50+ zeemetrikhi, ezihlangabezana neemfuno zehlabathi.

3. Ukuphathwa Okukhethekileyo kunye nokuPakisha

• Indawo yokugcina: Ithunyelwa kwiikhonteyina ezivaliweyo, ezihambelana netyathanga elibandayo.

• Ukupakisha: Iibhotile zeglasi ezi-amber okanye iidrama zentsimbi engatyiwayo phantsi kwe-nitrogen.

4. Inkxaso yoBugcisa kunye nokwenza ngokwezifiso

• Izisombululo ezenzelwe wena (umz., ii-odolo ezininzi, iifomyula ezilungisiweyo).

• I-SDS, i-COA, kunye namaxwebhu olawulo anikiwe.

Izikhokelo zoKhuseleko kunye nezoThutho

• Indawo yokugcina: Mayigcinwe kwi--20°C; kuphephe ukuvezwa kumswakama/umoya.

• Uthutho: Luhlelwe njengezinto eziyingozi (UN 3286). Ifuna:

  • Izinto ezisetyenziswa kwi-cold chain (iilori ezifakwe umkhenkce owomileyo okanye ezifakwe efrijini).

  • Isithuba sentloko segesi engasebenziyo (N₂) kwiphakheji.

  • Ukuthobela imimiselo ye-IATA/ADR yokuthutha impahla ngomoya/emhlabeni.

Isiphelo

Njengomvelisi ohamba phambili waseTshayina weDiethylaminosulfur Trifluoride (DAST, CAS 38078-09-0), sidibanisa imveliso ephezulu, ubunyulu obugqwesileyo, kunye nothungelwano oluqinileyo lwe-cold-chain ukuze sikhonze abathengi behlabathi. Nokuba kukwi-R&D yamayeza okanye kwi-fluorination yemizi-mveliso, i-DAST yethu inika ukuthembeka okungenakuthelekiswa nanto.
