Intshayelelo
I-2-Amino-4-cyanopyridine i-organic compound. Yikristale eqinileyo emhlophe inyibilika kancinane emanzini kwaye inokunyibilika kwizinyibilikisi zendalo ezifana neealkoholi kunye neeketones.
I-2-Amino-4-cyanopyridine ingasetyenziselwa ukuhlanganiswa kwamanye ama-compounds kwaye inoluhlu olubanzi lwezicelo kwi-organic synthesis.
Ukulungiswa kwe-2-amino-4-cyanopyridine inokufumaneka nge-hydrogenation kunye ne-nitrosation ye-pyridine. Okokuqala, i-pyridine kunye ne-hydrogen i-hydrogenated phantsi kwesenzo se-catalyst ukwenza i-2-amino derivative ye-pyridine. Isiphumo se-2-aminopyridine emva koko sisabela nge-asidi ye-nitrous ukuvelisa i-2-amino-4-cyanopyridine.
Kuphephe ukudibana nolusu kunye namehlo njengoko kunokuba nefuthe elicaphukisayo eluswini kunye namehlo.
Iiglavu ezikhuselayo kunye neglavu kufuneka zinxitywe xa zisetyenziswa, kwaye ziqinisekise ukuba utyando lwenziwa kwindawo engena umoya.
Kuphephe ukuphefumla uthuli kwaye unxibe imaski ekhuselayo.
Kwimeko yokuphefumla ngempazamo okanye ukungeniswa kwale khompawundi, funa unyango ngokukhawuleza.
Nceda ugcine ikhompawundi ngokufanelekileyo, kude nomlilo kunye nee-oxidants, kwaye kwindawo eyomileyo, epholileyo.
