5-Bromo-2-3-dichloropyridine CAS 97966-00-2

Zizindikiro Zowopsa	R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. R41 - Kuopsa kwa kuwonongeka kwakukulu kwa maso R37/38 - Zokwiyitsa dongosolo la kupuma ndi khungu. R25 - Poizoni ngati atamezedwa
Kufotokozera Zachitetezo	S26 - Mukakhudzana ndi maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S45 - Pakachitika ngozi kapena ngati simukumva bwino, funsani upangiri wachipatala nthawi yomweyo (onetsani chizindikirocho ngati kuli kotheka.) S39 - Valani chitetezo chamaso / kumaso.
Kalasi Yowopsa	ZOKHUDZA

5-bromo-2,3-dichloropyridine ndi organic pawiri ndi mankhwala chilinganizo C5H2BrCl2N. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha gululi:

Chilengedwe:
-Maonekedwe: Opanda utoto mpaka kuwala kowala wachikasu kapena ufa wonyezimira
-Kusungunuka: 62-65°C
-Kutentha kotentha: 248°C
-Kuchulukana: 1.88g/cm³
- osasungunuka m'madzi, osungunuka mu zosungunulira za organic (monga chloroform, methanol, ether, etc.)

Gwiritsani ntchito:
- 5-bromo-2,3-dichloropyridine ndi yofunika wapakatikati mu kaphatikizidwe organic.
-Itha kugwiritsidwa ntchito pokonzekera zolembedwa zokhala ndi mpweya wa radioactive carbon isotopes.

Njira Yokonzekera:
Kukonzekera njira -5-bromo-2,3-dichloropyridine zambiri akamagwira bromination m'malo anachita 2,3-dichloro-5-nitropyridine. Njira yeniyeni ndi kuyamba kuchita 2,3-dichloro-5-nitropyridine ndi phosphorous trichloride, ndiyeno kuchita bromination m'malo anachita ndi bromine.

Zambiri Zachitetezo:
- 5-bromo-2,3-dichloropyridine ndi organic pawiri ndipo ayenera kutsatira njira otetezeka ntchito pogwira ndi ntchito.
-Zitha kukhala zokhumudwitsa m'maso, pakhungu komanso m'mapumidwe, choncho valani magalasi, ma gloves ndi mask.
-Chonde sungani bwino, kutali ndi moto, kutentha ndi okosijeni, ndipo pewani kukhudzana ndi asidi amphamvu ndi alkali.
-Akapuma kapena kukhudza mwangozi, yeretsani malo omwe akhudzidwa nthawi yomweyo ndikupempha thandizo lachipatala.
