Mawu Oyamba
5-Bromo-2,3-diaminopyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: 5-Bromo-2,3-diaminopyridine ndi yoyera mpaka kuwala chikasu crystalline kapena crystalline ufa.
- Kusungunuka: Pawiriyi ndi yosungunuka pang'ono m'madzi ndipo imakhala yabwino kusungunuka mu zosungunulira za organic.
Gwiritsani ntchito:
- 5-Bromo-2,3-diaminopyridine amagwiritsidwa ntchito ngati reagent mu organic synthesis reactions.
- Itha kugwiritsidwa ntchito ngati wapakatikati pakupanga kophatikizana kophatikizana kapena zothandizira.
Njira:
Kukonzekera kwa 5-bromo-2,3-diaminopyridine kungapezeke mwa njira zotsatirazi:
1. Sungunulani 2,3-diaminopyridine mu kuchepetsa hydrochloric acid poyamba.
2. Sodium nitrite ndiye amawonjezeredwa kupanga mankhwala a nitroso.
3. Pansi pa madzi osambira a ayezi, bromide ya potaziyamu imawonjezeredwa kuti ipange 5-bromo-2,3-diaminopyridine.
Zambiri Zachitetezo:
- 5-Bromo-2,3-diaminopyridine ndi organic pawiri kuti ayenera kusungidwa ndi kugwiritsidwa ntchito moyenera kupewa kukhudzana ndi khungu ndi maso.
- Pogwira ntchito, njira zodzitetezera ku labotale ziyenera kutsatiridwa, monga kuvala zida zodzitetezera zoyenera (mwachitsanzo, magolovesi, magalasi, malaya a labu, ndi zina).
- Gwirani zinthuzo m'njira yoti mupewe ngozi zomwe zingabwere chifukwa chokoka mpweya, kumeza, kapena kukhudza.
Pakufufuza kwamankhwala ndi kuyesa, ndikofunikira kuchita ntchito yabwino yoyang'anira chitetezo cha labotale ndikugwira ntchito motsatira malangizo a akatswiri.
