-Indawo yokunyibilika:-3 ℃
-Indawo yokubila: 204-205 ℃
-Ubuninzi: 1.518g/cm³
-Ukunyibilika: Inyibilika kancinci emanzini, inyibilika kwizinto ezininzi ezinyibilikayo
Sebenzisa:
Isetyenziswa ikakhulu kwi-organic synthesis njengento ebalulekileyo ephakathi. Ingasetyenziselwa ukwenza iziyobisi, izitshabalalisi kunye nezinye iikhompawundi eziphilayo.
Indlela:
Indlela yokulungiselela imi ngolu hlobo lulandelayo:
1. Nge-2-fluoropyridine kunye nenani elithile le-methyl bromide phambi kwe-oxidant chlorine okanye i-carbon peroxide reaction.
2. Ilungiselelwe ngokuphendula kwe-2-bromo-5-fluoropyridine kunye ne-methyl lithium.
Ulwazi ngoKhuseleko:
Inokucaphukisa kunye nokutshabalalisa umzimba womntu, ngoko kufuneka ubeke ingqalelo kumanyathelo okhuseleko xa uyisebenzisa, kubandakanywa nokunxiba iiglavu zokukhusela, iiglasi kunye nempahla yokukhusela. Kuphephe ukuphefumla umphunga wayo okanye ukudibana nolusu namehlo. Ukuba i-inhaled okanye ibonakaliswe kwi-compound, hlamba indawo echaphazelekayo ngokukhawuleza kwaye ufune uncedo lwezonyango ukuba kuyimfuneko.
