Mawu Oyamba
2-bromo-4-methylpyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
2-Bromo-4-methylpyridine ndi madzi opanda mtundu mpaka achikasu omwe amanunkhira kwambiri. Ndi sungunuka mu organic solvents ndi insoluble m'madzi. Ndi mankhwala omwe ali ndi kawopsedwe kochepa.
Gwiritsani ntchito:
2-Bromo-4-methylpyridine nthawi zambiri amagwiritsidwa ntchito popanga organic synthesis monga chofunikira chapakati. Lili ndi ntchito zambiri zomwe zimagwiritsidwa ntchito popanga mankhwala a heterocyclic ndi mamolekyu ogwira ntchito.
Njira:
Ambiri a kukonzekera njira 2-bromo-4-methylpyridine ndi zimene kolorayidi ndi potaziyamu bromidi kapena bromic asidi, ndi mankhwala akamagwira m'malo anachita.
Chidziwitso cha Chitetezo: Zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zishango zakumaso ziyenera kuvalidwa zikagwiritsidwa ntchito. Posunga ndikugwira, kukhudzana ndi okosijeni ndi ma asidi amphamvu kuyenera kupewedwa. Iyeneranso kusungidwa kutali ndi malawi osatsegula ndi magwero oyatsira. 2-Bromo-4-methylpyridine ndi yabwino kugwiritsa ntchito ikagwiritsidwa ntchito ndikusungidwa bwino.
