Tlhaho:

-Ponahalo: 2-Fluoro-5-nitropyridine ke 'mala o mosoeu ho isa ho o mosehla o mosehla.

-Solubility: E ka qhibiliha ka metsoako e mengata ea lintho tse phelang, tse kang ethanol, dimethylformamide le dichloromethane.

- Sebaka sa ho qhibiliha: Sebaka sa eona sa ho qhibiliha se ka ba likhato tse 78-81 tsa Celsius.

 

Sebelisa:

- 2-Fluoro-5-nitropyridine ke motsoako o sebetsang hantle oa organic synthesis, o nang le ts'ebeliso ea bohlokoa tlhahisong ea lithethefatsi le chefo e bolaeang likokoanyana.

-E ka sebelisoa ho kopanya mefuta e fapaneng ea metsoako e sebetsang ea biologically, joalo ka meriana, dae le litlolo.

 

Mokhoa oa ho itokisa:

- 2-Fluoro-5-nitropyridine ka kakaretso e lokiselitsoe ke fluorination le nitrate ea pyridine.

-Mokhoa o khethehileng oa ho itokisa o ka 'na oa arabela pyridine ka hydrogen fluoride kapa ammonium fluoride ho fumana 2-fluoropyridine. Joale 2-fluoropyridine e arabela ka asiti ea nitric ho fana ka 2-Fluoro-5-nitropyridine.

 

Lintlha tsa Tšireletseho:

- 2-Fluoro-5-nitropyridine ke motsoako oa tlhaho o nang le tekanyo e itseng ea kotsi. Nakong ea ts'ebetso, hoa hlokahala ho latela melao e nepahetseng ea ts'ebetso ea ts'ireletso.

-E ka 'na ea halefisa letlalo le mahlo, kahoo mehato ea tšireletso e lokela ho nkoa ha e pepesitsoe, e kang ho apara li-gloves tse sireletsang le likhalase.

-Haeba motho a kene ka phoso kapa a hema, batla thuso ea bongaka 'me u fane ka mehato e loketseng ea thuso ea pele.

-Nakong ea polokelo, 2-Fluoro-5-nitropyridine e lokela ho bolokoa sebakeng se omeletseng, se pholileng, hole le mollo le li-oxidizing agents.
