Mawu Oyamba
5-Amino-2-bromo-3-picoline ndi organic pawiri ndi mankhwala chilinganizo C7H8BrN2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
5-Amino-2-bromo-3-picolini ndi yolimba yokhala ndi mawonekedwe akristalo oyera mpaka otuwa. Ikhoza kusungunuka mu mowa wa anhydrous, ethers ndi chlorinated hydrocarbons, kusungunuka kochepa m'madzi. Malo ake osungunuka ndi pafupifupi madigiri 74-78 Celsius.
Gwiritsani ntchito:
5-Amino-2-bromo-3-picoline, monga pawiri wapakatikati, amagwiritsidwa ntchito kwambiri mu organic synthesis. Itha kugwiritsidwa ntchito ngati poyambira zinthu kapena mankhwala apakatikati a organic synthesis reaction, ndipo itha kugwiritsidwa ntchito kupanga mitundu yosiyanasiyana ya nayitrogeni, utoto wa fulorosenti, mankhwala ndi mankhwala ena. Mwachitsanzo, angagwiritsidwe ntchito pokonza mankhwala ophera tizilombo, utoto, mankhwala ndi zina zotero.
Njira Yokonzekera:
Kukonzekera njira ya 5-Amino-2-bromo-3-picoline chingapezeke ndi bromination anachita pyridine. A wamba kupanga njira ndi kuchita pyridine ndi asidi bromoacetic, pamaso pa asidi, kupereka mankhwala 5-Amino-2-bromo-3-picoline.
Zambiri Zachitetezo:
Maphunziro a chitetezo pa 5-Amino-2-bromo-3-picolini ndi ochepa. Komabe, monga organic pawiri, chonde tsatirani malamulo otetezedwa ku labotale mukamagwira, kuphatikiza kuvala zida zoyenera zodzitetezera kuti mupewe kupuma, kukhudzana ndi khungu ndi kudya. Iyenera kusungidwa pamalo owuma, amdima ndikusiyanitsidwa ndi zowonjezera zowonjezera, ma asidi amphamvu ndi maziko amphamvu.
