5-Bromo-2,4-dichloropyrimidine ndi organic pawiri.
Ubwino:
- Maonekedwe: 5-Bromo-2,4-dichloropyrimidine ndi woyera crystalline olimba.
- Kusungunuka: 5-Bromo-2,4-dichloropyrimidine imakhala ndi kusungunuka kochepa m'madzi ndipo imasungunuka mu zosungunulira za organic monga ethanol ndi acetone.
Gwiritsani ntchito:
- Mankhwala ophera tizilombo: 5-bromo-2,4-dichloropyrimidine angagwiritsidwe ntchito ngati mankhwala chigawo chimodzi cha heterocyclic mankhwala, makamaka kulamulira udzu m'madzi ndi yotakata sipekitiramu namsongole.
Njira:
The synthesis wa 5-bromo-2,4-dichloropyrimidine angathe kuchitidwa ndi njira zosiyanasiyana, njira wamba ndi kuchita 2,4-dichloropyrimidine ndi bromine. Izi zimachitika kawirikawiri ndi sodium bromide.
Zambiri Zachitetezo:
- 5-Bromo-2,4-dichloropyrimidine imatha kuwola pakatentha kwambiri, kupanga mpweya wapoizoni wa hydrogen chloride. Kutentha kwakukulu ndi zidulo zamphamvu ziyenera kupewedwa panthawi yogwira ndi kusunga.
- 5-Bromo-2,4-dichloropyrimidine imakwiyitsa maso ndi khungu ndipo iyenera kupewedwa. Magolovesi otetezera oyenerera, magalasi, ndi malaya a labu ayenera kuvala panthawi yogwira ntchito.
