Intshayelelo
I-2-chloro-5-aminopyridine yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-2-chloro-5-aminopyridine yinto eqinileyo yekristale engenambala.
- Ukunyibilika: Inonyibiliko oluphantsi emanzini kodwa inokunyibilika kwizinyibilikisi ze-organic ezifana ne-ethanol kunye ne-chloroform.
Sebenzisa:
- I-2-chloro-5-aminopyridine idla ngokusetyenziswa njengendawo ephakathi kwi-synthesis yezinye iikhompawundi.
Indlela:
Indlela yokulungiselela i-2-chloro-5-aminopyridine ngokuqhelekileyo ibandakanya i-nucleophilic substitution reaction ye-2-chloropyridine. Indlela esetyenziswa ngokuqhelekileyo kukusabela kwi-2-chloropyridine nge-ammonia. Ukuphendula kunokuqhutyelwa kwi-solvent efanelekileyo kunye neqondo lokushisa elifanelekileyo.
Ulwazi ngoKhuseleko:
- I-2-chloro-5-aminopyridine yinto ephilayo enokuthi ibe yingozi ebantwini. Xa usetyenziswa, kufuneka ulandele iinkqubo zokusebenza ezifanelekileyo zokhuseleko kwaye unxibe izixhobo zokukhusela ezifana neeglavu, iimaski, kunye nezibuko.
- Kuphephe ukudibana nolusu kunye namehlo. Kwimeko yokudibanisa ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi.
- Ikhompawundi kufuneka igcinwe kwaye iphathwe ngendlela ethintela ukudibana ne-oxidants kunye ne-acids eqinile ukuphepha ukuphendula kweekhemikhali ezingakhuselekanga.
Xa usebenzisa kunye nokuphatha i-2-chloro-5-aminopyridine okanye nayiphi na ikhemikhali, soloko ubhekisela kwiiNkcukacha zoKhuseleko ezifanelekileyo kunye nezikhokelo zokuphathwa kwebhubhoratri kwaye ulandele amanyathelo okhuseleko afanelekileyo.
