3-Bromo-2-fluoro-5-methylpyridine (CAS# 17282-01-8)

Zizindikiro Zowopsa	R20/21/22 - Zowopsa pokoka mpweya, kukhudzana ndi khungu komanso kumeza. R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. R41 - Kuopsa kwa kuwonongeka kwakukulu kwa maso R37/38 - Zokwiyitsa dongosolo la kupuma ndi khungu. R22 - Zowopsa ngati zitamezedwa
Kufotokozera Zachitetezo	S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S36 - Valani zovala zoyenera zodzitetezera. S39 - Valani chitetezo chamaso / kumaso.
Kalasi Yowopsa	ZOKWIYA

Ndi organic pawiri ndi mankhwala formula C6H5BrFN. Zotsatirazi ndikulongosola za chikhalidwe chake, kagwiritsidwe ntchito, kukonzekera ndi chidziwitso cha chitetezo:Chilengedwe:
ndi madzi achikasu otumbululuka opanda mtundu. Imakhala ndi fungo loipa kwambiri pa kutentha kwapakati. Kuchulukana kwa pawiri ndikwambiri, ndipo malo ake osungunuka ndi malo otentha amawonjezeka ndi kuchuluka kwa bromine.

Gwiritsani ntchito:
Amagwiritsidwa ntchito ngati reagent kapena wapakatikati mu organic synthesis. Angagwiritsidwe ntchito pokonza mankhwala, mankhwala ndi zina organic mankhwala. Itha kugwiritsidwanso ntchito ngati reagent mu kafukufuku ndi ma laboratories.

Njira:
Njira yopangira mapiritsi makamaka imaphatikizapo njira ziwiri. Choyamba, bromomethylpyridine imayendetsedwa ndi potaziyamu fluoride mu zosungunulira za organic kuyambitsa atomu ya fluorine. The chifukwa bromofluoro pawiri ndiye oxidized kwa lolingana halogen ndi hydrogen peroxide kapena oxidizing mankhwala.

Zambiri Zachitetezo:
Ndi organic pawiri ndipo ayenera kusamalidwa mosamala. Pogwiritsa ntchito kapena kukonzekera, njira zotetezera ziyenera kuchitidwa, monga kuvala magolovesi oteteza mankhwala, magalasi ndi makina otulutsa mpweya kunja kwa labotale. Pewani kukhudza khungu ndi maso, ndipo pewani moto. Posunga, chidebecho chizikhala chotsekedwa ndikuchiyika pamalo ozizira komanso owuma. Mukameza kapena kukhudza khungu, pitani kuchipatala mwamsanga.
