3-Bromo-2-chloro-5-(trifluoromethyl)pyridine(CAS# 71701-92-3)
Ngozi ndi Chitetezo
| Zizindikiro Zowopsa | R25 - Poizoni ngati atamezedwa R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. |
| Kufotokozera Zachitetezo | S7/9 - S22 - Osapumira fumbi. S24/25 - Pewani kukhudzana ndi khungu ndi maso. S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S36/37 - Valani zovala zoyenera zodzitchinjiriza ndi magolovesi. S38 - Ngati mulibe mpweya wokwanira, valani zida zoyenera zopumira. S45 - Pakachitika ngozi kapena ngati simukumva bwino, funsani upangiri wachipatala nthawi yomweyo (onetsani chizindikirocho ngati kuli kotheka.) S51 - Gwiritsani ntchito m'malo olowera mpweya wabwino. |

Mawu Oyamba
Pawiri ali zofunika ntchito pa kaphatikizidwe mankhwala ndi kaphatikizidwe mankhwala. Angagwiritsidwe ntchito ngati wapakatikati kwa synthesis wa biologically yogwira mankhwala. Mwachitsanzo, itha kugwiritsidwa ntchito popanga mankhwala opha tizilombo toyambitsa matenda ndi mankhwala ophera tizilombo, etc.
The 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine ikhoza kukonzedwa ndi njira zosiyanasiyana. Njira yodziwika bwino ndiyo kuyambitsa maatomu a bromine ndi klorini pochita ndi bromination ndi chlorination, motero, kuyambira ndi pyridine. Kenako, gulu la trifluoromethyl limayambitsidwa munjira ya trifluoromethylation. Izi kaphatikizidwe zambiri ikuchitika pansi inert mpweya kuonetsetsa mkulu selectivity ndi zokolola za anachita.
The 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine ili ndi chidziwitso chochepa cha chitetezo. Zitha kukhala zokhumudwitsa m'maso, kupuma komanso khungu. Pogwiritsa ntchito, chisamaliro chiyenera kutengedwa kuti musagwirizane ndi khungu ndi maso. Panthawi imodzimodziyo, njira zodzitetezera ziyenera kuchitidwa panthawi ya ntchito, monga kuvala magalasi otetezera, magolovesi ndi zovala zotetezera.
Kuonjezera apo, pakugwira ntchito ndi kusunga, chisamaliro chiyenera kutengedwa kuti zisagwirizane ndi zipangizo zoyaka moto komanso kusunga mpweya wabwino. Potaya zinyalala, malamulo amderalo ayenera kutsatiridwa ndipo njira zoyenera zotayira zinyalala ziyenera kutsatiridwa. Amagwiritsidwa ntchito bwino ndikusamalidwa motsogozedwa ndi akatswiri odziwa zamankhwala.
