Mawu Oyamba
2-Chloro-3-amino-5-bromopyridine ndi organic pawiri. Zotsatirazi ndizofotokozera mwachidule za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: Makristalo oyera mpaka otumbululuka achikasu
- Kusungunuka: Kusungunuka mu chloroform ndi ethanol, kusungunuka pang'ono m'madzi
Gwiritsani ntchito:
- Pawiriyi itha kugwiritsidwanso ntchito ngati chothandizira pakuphatikizika kwachilengedwe ndipo imakhala ndi gawo lofunikira pakuphatikizika kwazinthu zina.
Njira:
- The synthesis wa 2-chloro-3-amino-5-bromopyridine zambiri ikuchitika ntchito chlorination-bromination anachita. Zimakonzedwa pochita 3-amino-4-bromopyridine ndi chlorinating agents (monga phosphorous trichloride, sulfuryl chloride, etc.).
Zambiri Zachitetezo:
- 2-Chloro-3-amino-5-bromopyridine ndi mankhwala ndipo amafuna kusamala koyenera monga kuvala magolovesi a mankhwala ndi masks.
- Mukamagwiritsa ntchito ndikusunga, kukhudzana ndi okosijeni, ma acid amphamvu, ndi ma alkali amphamvu kuyenera kupewedwa kuti mupewe zoopsa.
- Ikhoza kukhala mankhwala omwe ndi owopsa pakhungu, maso, ndi kupuma, ndipo ayenera kutsukidwa ndi madzi mwamsanga mutangowakhudza ndipo chithandizo chamankhwala chiyenera kufunidwa.
