2-METHOXY-3 5-DIBROMO-PYRIDINE (CAS# 13472-60-1)

Zizindikiro Zowopsa	R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. R41 - Kuopsa kwa kuwonongeka kwakukulu kwa maso R22 - Zowopsa ngati zitamezedwa
Kufotokozera Zachitetezo	S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S36 - Valani zovala zoyenera zodzitetezera. S45 - Pakachitika ngozi kapena ngati simukumva bwino, funsani upangiri wachipatala nthawi yomweyo (onetsani chizindikirocho ngati kuli kotheka.)

3,5-Dibromo-2-methoxypyridine (yomwe imadziwikanso kuti 2-bromo-3, 5-dimethoxypyridine) ndi mankhwala achilengedwe. Ili ndi mawonekedwe a mamolekyu a C7H6Br2NO ndi kulemera kwa molekyulu ya 264.94g / mol.3,5-Dibromo-2-methoxypyridine ndi yolimba yokhala ndi makristasi oyera achikasu. Zitha kusungunuka mu zosungunulira zina organic kutentha firiji, monga chloroform, etha ndi methanol.The ntchito yaikulu pawiri ndi monga wapakatikati ndi reagent mu kaphatikizidwe organic. Itha kugwiritsidwa ntchito popanga mankhwala osiyanasiyana, mankhwala ophera tizilombo, utoto ndi zinthu zina zachilengedwe.

Njira yopangira 3,5-dibromo-2-methoxypyridine nthawi zambiri imapezeka pochita 3,5-dibromopyridine ndi methanol. Zomwe zimachitikira zitha kuchitidwa pansi pamlengalenga pa kutentha koyenera komanso nthawi.

Ponena za chitetezo, 3,5-dibromo-2-methoxypyridine ndi chinthu chowopsa. Zitha kuyambitsa mkwiyo ndi dzimbiri mthupi la munthu, komanso zitha kukhala zovulaza chilengedwe. Pogwiritsira ntchito ndikugwira, njira zotetezera ziyenera kuchitidwa, monga kuvala magolovesi otetezera, magalasi ndi zovala zotetezera, kuonetsetsa kuti mpweya wabwino umalowa bwino, komanso kupewa kukhudzana ndi khungu ndi maso. Kuonjezera apo, njira zoyenera zosungira ndi zowonongeka ziyenera kutsimikiziridwa kuti ziteteze ngozi ndi kuipitsidwa. Musanagwiritse ntchito, ndi bwino kutchula pepala lachitetezo chamankhwala kuti mudziwe zambiri zachitetezo.
