2,3-Dichloro-5-nitropyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:

 

Boleng:

- Ponahalo: 2,3-dichloro-5-nitropyridine ke kristale e khanyang e khanyang kapa phofo ea crystalline e se nang mebala.

- Ho qhibiliha: Ho qhibiliha ka har'a lihlapolli tsa tlhaho tse kang chloroform, ethanol, ether le benzene.

 

Sebelisa:

- Li-preservatives: E boetse e na le phello e thibelang likokoana-hloko 'me e ka ekeletsoa lihlahisoa tse ling tse kang lipente, lehong le polasetiki, har'a tse ling.

 

Mokhoa:

- Ka tloaelo, 2,3-dichloro-5-nitropyridine e fumanoa ka ho arabela 2,3-dichloropyridine ka nitric acid.

- Ts'ebetso e ikhethileng ea ho itokisa e kanna ea kenyelletsa maemo a itseng a karabelo le li-catalyst, mme lintlha tse ikhethileng li tlameha ho etsoa ka laboratoring ea lik'hemik'hale.

 

Lintlha tsa Tšireletseho:

- 2,3-Dichloro-5-nitropyridine ke motsoako oa lintho tse phelang o hlokang ho khomarela tšebeliso e nepahetseng le ho sebetsana le lik'hemik'hale, tse kang ho apara li-gloves tse sireletsang, likhalase le seaparo sa lab.

- Ha e bolokoa, e lokela ho bolokoa sebakeng se omeletseng, se phodileng le hole le mollo le li-oxidants.

- Qoba ho hema, ho koenya, kapa ho kopana le letlalo le mahlo nakong ea ts'ebeliso.
