Ndi organic pawiri. Kapangidwe kake kake kamakhala ndi mphete ya pyridine yokhala ndi amino (NH2) Gulu, atomu ya bromine ndi gulu la Nitro (NO2) lomwe limalumikizidwa ndi imodzi mwa ma atomu a kaboni.

Zina mwazinthu zapawirizi ndi izi:

1. Maonekedwe: wotumbululuka wachikasu mpaka lalanje-chikasu crystalline ufa.
2. Malo osungunuka: malo ake osungunuka a 80-86 digiri Celsius.
3. Kusungunuka: Ikhoza kusungunuka muzitsulo zambiri za organic, monga ethanol, methanol, ndi zina zotero. Kusungunuka kwake m'madzi kumakhala kochepa.

Ili ndi ntchito ina mu organic synthesis. Itha kugwiritsidwa ntchito ngati zopangira pawiri mu kaphatikizidwe ka organic, kutenga nawo mbali pamachitidwe osiyanasiyana amankhwala, ndikupanga mitundu yosiyanasiyana yama organic kapena intermediates.

Njira kukonzekera kashiamu zambiri ikuchitika ndi nucleophilic m'malo anachita. Njira imodzi yodziwika bwino yokonzekera ndikuchita 3-bromo-2-nitropyridine ndi amino pawiri kupanga chinthu chomwe mukufuna.

Ponena za chidziwitso cha chitetezo, ndi organic pawiri yomwe ingakhale ndi poizoni wina komanso kuyabwa. Njira zopewera chitetezo monga magolovesi osamva mankhwala, magalasi ndi mpweya wabwino zimafunikira panthawi yogwira ndikugwiritsa ntchito. Panthawi imodzimodziyo, iyenera kusungidwa mu chidebe chosindikizidwa, kutali ndi magwero a moto ndi zinthu zina zoyaka moto. Ngati mwakhudza kapena kumwa mowa mwadala, pitani kuchipatala mwamsanga. Nthawi zonse tsatirani njira zoyenera zotetezera, monga kutaya koyenera kwa zotsala kapena zinyalala.
