2-Fluoro-5-nitropyridine（CAS# 456-24-6)

Folasaga

2-Fluoro-5-nitropyridine (2-Fluoro-5-nitropyridine) o se vailaʻau faʻasolosolo faʻatasi ma le vailaʻau vailaʻau C5H3FN2O2. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:

natura:

-Fa'aaliga: 2-Fluoro-5-nitropyridine o se pa'epa'e i le lanu samasama mumu.

-Solubility: E mafai ona faʻamavaeina i le tele o vailaʻau faʻasolosolo, e pei o le ethanol, dimethylformamide ma le dichloromethane.

-Melting point: O lona liusuavai e tusa ma le 78-81 tikeri Celsius.

Fa'aaogā:

- 2-Fluoro-5-nitropyridine o se faʻaogaina lelei o le faʻaogaina o meaola, lea e faʻaaogaina taua i le gaosiga o vailaʻau ma vailaau faʻasaina.

-E mafai ona faʻaaogaina e faʻapipiʻi ai le tele o mea faʻapitoa faʻaolaola, e pei o vailaʻau, vali ma ufiufi.

Sauniuniga auala:

- 2-Fluoro-5-nitropyridine e masani ona saunia e le fluorination ma le faʻamaʻiina o pyridine.

-O le auala faʻapitoa sauniuni e mafai ona tali atu i le pyridine ma le hydrogen fluoride poʻo le ammonium fluoride e maua ai le 2-fluoropyridine. O le 2-fluoropyridine ona faʻafoʻi lea i le nitric acid e tuʻuina atu ai le 2-Fluoro-5-nitropyridine.

Fa'amatalaga Saogalemu:

- 2-Fluoro-5-nitropyridine o se faʻalapotopotoga faʻapitoa ma se tulaga faʻapitoa o lamatiaga. I le faagasologa o le faʻagaioiga, e manaʻomia le usitaʻia o tulafono faatonutonu talafeagai mo le saogalemu.

-E ono afaina ai le paʻu ma mata, o lea e tatau ai ona faia ni puipuiga pe a faʻaalia, e pei o le ofuina o totigilima ma mata tioata.

-Afai na fa'afuase'i ona 'ai pe manavaina, saili togafitiga fa'afoma'i ma tu'u atu ni faiga fesoasoani muamua talafeagai.

-I le taimi o le teuina, 2-Fluoro-5-nitropyridine e tatau ona teuina i se nofoaga matutu, malulu, ese mai afi ma faʻamaʻi faʻamaʻi.
