Mawu Oyamba

5-Fluoro-2-hydroxypyridine ndi organic pawiri ndi mankhwala chilinganizo C5H4FN2O. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:

 

Chilengedwe:

-5-Fluoro-2-hydroxyypyridine ndi yopanda mtundu mpaka yachikasu pang'ono.

-Kulemera kwake kwa maselo ndi 128.10g / mol.

-Imakhala ndi fungo lofooka.

-Imasungunuka m'madzi potentha.

 

Gwiritsani ntchito:

-5-Fluoro-2-hydroxyypyridine angagwiritsidwe ntchito ngati yofunika wapakatikati mu kaphatikizidwe organic.

-Nthawi zambiri amagwiritsidwa ntchito ngati chinthu chofunikira kwambiri pakupanga mankhwala opangira mankhwala.

-Itha kugwiritsidwanso ntchito popanga utoto, utoto ndi mankhwala ena.

 

Njira Yokonzekera:

-Njira yokonzekera yomwe imagwiritsidwa ntchito kawirikawiri ndiyo kupanga 5-Fluoro-2-hydroxypyridine pochita 2-amino-5-fluoropyridine ndi wothandizira oxidizing pansi pazikhalidwe zoyenera.

 

Zambiri Zachitetezo:

- 5-Fluoro-2-hydroxypyridine iyenera kusungidwa pamalo owuma, olowera mpweya wabwino.

-Valani zida zodzitetezera zoyenera monga magolovesi, magalasi ndi zovala zodzitchinjiriza mukamagwira ntchito ndikugwiritsa ntchito.

-Pewani kutulutsa fumbi kapena mpweya wake, komanso pewani kukhudza khungu ndi maso.

-Ngati mwangozi walowa m'maso kapena pakhungu, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.

-Chonde sungani bwino ndikuwerenga mosamala pepala lake lachitetezo musanagwire kapena kunyamula.
