Intshayelelo
I-5-Amino-2-bromo-3-picoline yi-organic compound kunye ne-chemical formula C7H8BrN2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
I-5-Amino-2-bromo-3-picoline iqinile kunye nefom yekristale emhlophe ukuya kwephuzi. Inokunyibilika kwi-alcohol e-anhydrous, i-ethers kunye ne-chlorinated hydrocarbons, ukunyibilika okuphantsi kwamanzi. Indawo yayo yokunyibilika imalunga ne-74-78 degrees Celsius.
Sebenzisa:
I-5-Amino-2-bromo-3-picoline, njenge-compound ephakathi, isetyenziswa ngokubanzi kwi-organic synthesis. Ingasetyenziswa njengesixhobo sokuqala okanye imveliso ephakathi ye-organic synthesis reaction, kwaye ingasetyenziselwa ukudibanisa iikhompawundi ezahlukeneyo ezine-nitrogen, iidayi ze-fluorescent, amayeza kunye nezinye iikhemikhali. Ngokomzekelo, inokusetyenziswa ekulungiseleleni izibulala-zinambuzane, idayi, amayeza kunye nezinto ezinjalo.
Indlela yokulungiselela:
Indlela yokulungiselela i-5-Amino-2-bromo-3-picoline inokufezekiswa ngokuphendula kwe-bromination ye-pyridine. Indlela eqhelekileyo yokwenziwa kukusabela kwi-pyridine kunye ne-bromoacetic acid, phambi kwe-asidi, ukunika imveliso ye-5-Amino-2-bromo-3-picoline.
Ulwazi ngoKhuseleko:
Izifundo zokhuseleko kwi-5-Amino-2-bromo-3-picoline zilinganiselwe. Nangona kunjalo, njengekhompawundi ephilayo, nceda ulandele imigaqo yokhuseleko lwaselabhoratri ngokubanzi xa uphatha, kubandakanya ukunxiba izixhobo ezifanelekileyo zokukhusela ukuphepha ukuphefumla, ukudibana nolusu kunye nokutya. Kufuneka igcinwe kwindawo eyomileyo, emnyama kwaye igcinwe ngokwahlukileyo kwi-oxidants, i-acids eqinile kunye neziseko ezinamandla.
