2-Bromo-3 5-dichloropyridine (CAS # 14482-51-0) ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, cholinga chake, njira yopangira, ndi chidziwitso cha chitetezo:

chilengedwe:

-Maonekedwe: 2-Bromo-3,5-dichloropyridine ndi kristalo yopanda mtundu kapena yoyera.

-Kusungunuka: 2-Bromo-3,5-dichloropyridine imasungunuka mu ethanol, etha, ndi chloroform.

Cholinga:

- Itha kugwiritsidwa ntchito ngati zopangira za fungicides ndi mankhwala ophera tizilombo.

Njira yopanga:

-2-bromo-3,5-dichloropyridine ikhoza kukonzedwa ndi njira zotsatirazi:

1. Yambani 3,5-dichloropyridine ndi bromine kuti mupeze 2-bromo-3,5-dichloropyridine pansi pamikhalidwe yoyenera.

Zambiri zachitetezo:

-2-Bromo-3,5-dichloropyridine ndi organic pawiri, ndipo chidwi chiyenera kulipidwa potsatira zofunikira zachitetezo cha labotale yamankhwala.

-Pogwiritsa ntchito, pewani kutulutsa fumbi lake komanso kukumana ndi khungu lowonekera.

-Ziyenera kusungidwa pamalo owuma, ozizira, opanda mpweya wabwino, kutali ndi kumene kumayaka moto ndi mankhwala ophera tizilombo toyambitsa matenda.

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 - Mukakhudza 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.
