2-methyll-5-nitropyridine ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C6H6N2O2, e nang le thepa e latelang:
1. Ponahalo: e se nang 'mala ho ea ho kristale e mosehla e khanyang;
2. Ho fofonela: ha ho monko o khethehileng;
3. Sebaka se qhibilihang: likhato tse 101-104 tsa Celsius;
4. Solubility: hoo e batlang e sa qhibilihe ka metsing, e qhibilihang ka har'a metsoako ea tlhaho e kang ethanol le dichloromethane.
2-Methyl-5-nitropyridine e sebelisoa haholo-holo e le thepa e tala le e bohareng ba lihlahisoa tsa tlhaho le indasteri ea meriana. E ka sebelisoa bakeng sa ho kopanya metsoako ea pyridine le thiophene, hape e ka sebelisoa bakeng sa ho lokisa chefo e bolaeang likokoanyana, lidae le metsoako e meng tšimong ea meriana.
Tokisetso ea 2-methyll-5-nitropyridine e ka etsoa ka mehato e latelang:
1.2-pyridine acetic acid le sodium nitrite li sebetsa tlas'a maemo a acidic ho hlahisa 2-nitropyridine.
2. Karabelo ea 2-Nitro pyridine e nang le methylating reagent (e kang methyl iodide) ho hlahisa 2-Methyl-5-nitropyridine.
Ha u sebelisa le ho boloka 2-methyll-5-nitropyridine, u lokela ho ela hloko lintlha tse latelang tsa polokeho:
-Ke ntho e tukang, qoba ho kopana le mollo;
-Ela hloko mehato ea ts'ireletso nakong ea ts'ebetso, joalo ka ho roala likhalase tse sireletsang le liatlana;
- qoba ho inhalation ea khase ea eona kapa lerōle, qoba ho kopana le letlalo;
- Boloka ka setshelo se koetsoeng, hole le mollo le li-oxidizing agents;
- Qoba ho kopana le li-oxidants tse matla kapa li-acid tse matla.
