Cov ntawv thov ntawm DAST

DAST yog ib qho reagent uas muaj ntau yam haujlwm tseem ceeb hauv:

1. Cov Tshuaj: Fluorination ntawm cov tshuaj intermediates (piv txwv li, steroids, antiviral compounds).

2. Cov tshuaj lom neeg ua liaj ua tebKev tsim cov tshuaj tua kab uas muaj fluorine thiab cov tshuaj tua kab.

3. Kev Tsim Khoom Siv OrganicKev xaiv cov fluorination ntawm cov cawv, carbonyls, thiab heterocycles.

4. Kev Tshawb Fawb Txog Cov Khoom SivKev Tsim Khoom ntawm fluoropolymers thiab cov kua siv lead ua kua.

Vim li cas ho xaiv peb DAST?

1. Qhov Zoo thiab Kev Huv Si Tsis Sib Xws

• Peb lub DAST raug kuaj xyuas HPLC/GC-MS kom paub tseeb tias muaj ≥98% purity, txo cov kev tsis haum tshuaj.

• Kev sib xws ntawm ib pawg mus rau ib pawg rau kev ua tau zoo txhim khu kev qha.

2. Muaj Peev Xwm Ntau Lawm Ntau

• Tuam Tshoj lub chaw tsim khoom DAST loj tshaj plaws nrog cov txheej txheem tau ntawv pov thawj ISO 9001.

• Txhua xyoo cov zis tawm ntawm 50+ metric tons, ua tau raws li qhov xav tau thoob ntiaj teb.

3. Kev Tswj Xyuas Tshwj Xeeb & Kev Ntim Khoom

• Kev Khaws Cia: Xa mus rau hauv cov thawv kaw, txias-saw-sib xws.

• Ntim: Lub raj mis iav xim av lossis cov nruas stainless-steel hauv qab nitrogen.

4. Kev Txhawb Nqa thiab Kev Kho Kom Haum

• Cov kev daws teeb meem uas tsim tshwj xeeb (piv txwv li, kev txiav txim ntau, cov qauv hloov kho).

• SDS, COA, thiab cov ntaub ntawv tswj hwm tau muab.

Cov Lus Qhia Txog Kev Nyab Xeeb & Kev Thauj Mus Los

• Kev Khaws Cia: Yuav tsum khaws cia rau ntawm -20 ° C; tsis txhob cia kom raug dej noo / cua.

• Kev Thauj Mus Los: Muab cais ua cov khoom phom sij (UN 3286). Yuav tsum muaj:

  • Kev xa khoom txias (dej khov qhuav los yog cov tsheb thauj khoom txias).

  • Qhov chaw ntawm cov roj inert (N₂) hauv cov ntim khoom.

  • Ua raws li IATA/ADR cov cai rau kev thauj khoom los ntawm huab cua/av.
