Selelekela
2-Bromoisoniacin, e tsejoang hape e le 2-bromopyridine-4-carboxylic acid, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 2-bromoisoniacinic acid:
Boleng:
- Ponahalo: 2-Bromoisoniacinic acid ke kristale e tiileng e tšoeu kapa e bosoeu.
- Sollubility: E ka qhibiliha ka har'a lihlapolli tsa tlhaho tse kang metsi, ethanol le ether.
- Thepa ea lik'hemik'hale: E ka fumana karabelo ea alkaline hydrolysis tlasa maemo a alkaline ho hlahisa metsoako e tsamaellanang ea bromopyridine.
Sebelisa:
- E ka boela ea sebelisoa e le dae e bohareng ha ho etsoa lidae le li-pigments.
Mokhoa:
- Mokhoa o tloaelehileng oa ho lokisetsa 2-bromoisoniacinic acid o fumanoa ka ho arabela 2-picolinic acid ka thionyl bromide. Kopanya 2-picolinic acid le sulfoxide ka har'a motsoako o loketseng 'me u kenye motsoako o itseng oa acidic. Joale, thionyl bromide e eketsoa butle-butle, 'me karabelo e etsahala. Tharollo ea karabelo e ile ea phekoloa hantle le ho hloekisoa ho fumana sehlahisoa sa 2-bromoisoniacinic acid se nang le bohloeki bo phahameng.
Tlhahisoleseding ka Polokeho: Ke ntho e tenang e ka bakang ho teneha le ho se phutholohe ha motho a kopana le letlalo, mahlo, kapa pampitšana ea ho hema. Lisebelisoa tse loketseng tsa ho itšireletsa tse kang liatlana, likhalase le lithebe tsa sefahleho li lokela ho aparoa ha li sebelisoa.
- Ha u tšoara 2-bromoisoniacin, qoba ho hema lerōle kapa mouoane oa eona. Ka mor'a phekolo, libaka le lisebelisoa tse silafetseng li lokela ho hloekisoa hantle.
- Poloko e nepahetseng ea 2-bromoisoniacin, e lokela ho bolokoa sebakeng se omeletseng, se phodileng le se nang le moea o motle, hole le ho khantša le li-oxidants. Boloka ka karohano le lintho tse tukang, li-acids le lisebelisoa tse fokotsang.
- Ha motho a ka hema ka phoso, ho pepeseha kapa ho nooa 2-bromoisoniacin, batla thuso ea bongaka hang-hang 'me u tlise litaelo kapa leibole ea sehlahisoa seo ho buuoang ka sona.
