4-Amino-3-bromopyridine (CAS # 13534-98-0) chiyambi
4-Amino-3-bromopyridine ndi organic pawiri ndi zotsatirazi katundu:
Maonekedwe: 4-Amino-3-bromopyridine ndi yolimba yachikasu.
Kusungunuka: Kumakhala ndi mulingo wina wa kusungunuka mu zosungunulira za polar monga madzi, ma alcohols, ndi ma ether.
Mankhwala katundu: 4-Amino-3-bromopyridine angagwiritsidwe ntchito ngati nucleophilic reagent mu organic kaphatikizidwe m'malo zimachitikira ndi kumanga maselo frameworks.
Cholinga chake:
Njira yopanga:
Pali njira zosiyanasiyana synthesizing 4-amino-3-bromopyridine, ndi wamba kukonzekera njira ndi kuchita 4-bromo-3-chloropyridine ndi anhydrous ammonia mu organic solvents.
Zambiri zachitetezo:
4-Amino-3-bromopyridine ndi organic pawiri ndi allergenic ndi zokwiyitsa katundu. Pogwira ntchito, ndikofunikira kuvala zida zoyenera zodzitetezera monga magolovesi ndi magalasi, ndikusunga mpweya wabwino.
Pewani kukhudza khungu ndipo pewani kutulutsa nthunzi kapena fumbi lake.
Samalani posunga ndi kunyamula, pewani kukhudzana ndi zinthu zomwe zimatha kuyaka, ndipo pewani kuwunjikana m'zidebe zotsekera.
