I-Diethylaminosulfur Trifluoride (DAST, CAS 38078-09-0) – Umkhiqizi Nomhlinzeki Ohamba Phambili waseShayina

Isingeniso

I-Diethylaminosulfur Trifluoride (DAST, CAS No. 38078-09-0) iyi-reagent ekhethekile kakhulu yokufudumeza esetshenziswa kabanzi kwezemithi, amakhemikhali ezolimo, kanye nokuhlanganiswa kwezinto eziphilayo. Njengomkhiqizi nomhlinzeki omkhulu we-DAST eShayina, sinikeza i-DAST emsulwa kakhulu ngokulawula ikhwalithi okuqinile, okuqinisekisa ukusebenza okuphezulu kwezicelo zezimboni nezocwaningo.

Izici Zomkhiqizo

• Ifomula Yamakhemikhali: (C₂H₅)₂NSF₃

• Inombolo ye-CAS: 38078-09-0

• Ubumsulwa: ≥98% (HPLC)

• Ukubukeka: Uketshezi olungenambala kuya koluphuzi olukhanyayo

• Isitoreji: Kudinga -20--2°C isiqandisiukuvimbela ukubola

• Ukuzinza: Izwela umswakama; kumele iphathwe ngaphansi kwegesi engasebenzi (N₂/Ar)

Izicelo ze-DAST

I-DAST iyi-reagent eguquguqukayo enezindima ezibalulekile ku:

1. Imithi: Ukushintshwa kwe-fluorination yezidakamizwa eziphakathi (isb., ama-steroid, ama-antiviral compounds).

2. Amakhemikhali ezolimo: Ukwenziwa kwezibulala-zinambuzane kanye nemithi yokubulala ukhula equkethe i-fluorine.

3. Ukwenziwa Kwezinto Eziphilayo: Ukushintshashintsha okukhethiwe kwama-alcohols, ama-carbonyl, nama-heterocycle.

4. Isayensi Yezinto Ezisetshenziswayo: Ukukhiqizwa kwama-fluoropolymers namakristalu e-liquid.

Kungani Kufanele Ukhethe I-DAST Yethu?

1. Ikhwalithi Nobumsulwa Obungalingani

• I-DAST yethu ihlolwa kanzima yi-HPLC/GC-MS ukuqinisekisa ubumsulwa obungu-≥98%, okunciphisa ukusabela okungekuhle.

• Ukuvumelana kweqembu ngalinye ukuze kusebenze kahle.

2. Amandla Okukhiqiza Athuthukile

• Isikhungo sokukhiqiza i-DAST esikhulu kunazo zonke eShayina esinezinqubo eziqinisekiswe yi-ISO 9001.

• Umkhiqizo waminyaka yonke wamathani angaphezu kwama-metric angu-50, ohlangabezana nesidingo somhlaba wonke.

3. Ukuphathwa Okukhethekile Nokupakisha

• Indawo Yokugcina: Kuthunyelwa ezitsheni ezivaliwe, ezihambisana nochungechunge olubandayo.

• Ukupakisha: Amabhodlela engilazi anombala ophuzi noma amadramu ensimbi engagqwali angaphansi kwe-nitrogen.

4. Ukusekelwa Kobuchwepheshe kanye Nokwenza Ngokwezifiso

• Izixazululo ezenzelwe wena (isb., ama-oda amaningi, amafomula aguquliwe).

• Kunikezwe imibhalo ye-SDS, COA, kanye nemithethonqubo.

Iziqondiso Zokuphepha Nokuhamba

• Indawo Yokugcina: Kufanele igcinwe ku--20°C; gwema ukuchayeka emswakama/emoyeni.

• Ezokuthutha: Zihlukaniswe njengezinto eziyingozi (UN 3286). Kudinga:

  • Izinto zokuthutha ezibandayo (iqhwa elomile noma amaloli aqandisiwe).

  • Isikhala sekhanda segesi engasebenzi (N₂) esisephaketheni.

  • Ukuthobela imithetho ye-IATA/ADR yokuthutha ngendiza/ngezwe.

Isiphetho

Njengomkhiqizi ohamba phambili waseShayina we-Diethylaminosulfur Trifluoride (DAST, CAS 38078-09-0), sihlanganisa ukukhiqizwa okuphezulu, ubumsulwa obumangalisayo, kanye nokuphathwa kwe-cold-chain eqinile ukuze sikhonze amakhasimende omhlaba wonke. Kungakhathaliseki ukuthi kungokwe-R&D yezemithi noma i-fluorination yezimboni, i-DAST yethu inikeza ukuthembeka okungenakuqhathaniswa.
