Folasaga
5-Bromo-2,3-diaminopyridine o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
Tulaga lelei:
- Faʻaaliga: 5-Bromo-2,3-diaminopyridine e paʻepaʻe ile lanu samasama samasama poʻo le paʻu tioata.
- Solubility: O le fa'aputuga e solu teisi i le vai ma e lelei lona soluble i solu fa'aola.
Fa'aaogā:
- 5-Bromo-2,3-diaminopyridine e masani ona faʻaaogaina e avea o se reagent i gaioiga faʻasolosolo faʻasolosolo.
- E mafai ona faʻaaogaina e avea o se vaeluagalemu i le tuʻufaʻatasia o faʻamaopoopo faʻapipiʻi poʻo catalysts.
Metotia:
O le sauniuniga o le 5-bromo-2,3-diaminopyridine e mafai ona ausia i laasaga nei:
1. Fa'amuta le 2,3-diaminopyridine i le fa'amama fa'amalo muamua.
2. Ona faaopoopo lea o le sodium nitrite e fausia ai nitroso compounds.
3. I lalo o tulaga taele vai aisa, faʻapipiʻi le potassium bromide e fai ai le 5-bromo-2,3-diaminopyridine.
Fa'amatalaga Saogalemu:
- 5-Bromo-2,3-diaminopyridine o se faʻalapotopotoga faʻapitoa e tatau ona teuina ma faʻaoga lelei e aloese ai mai le faʻafesoʻotaʻi ma le paʻu ma mata.
- Pe a fa'agaioi, e tatau ona faia ni faiga lelei mo le saogalemu o falesu'esu'e, e pei o le ofuina o mea e puipuia ai (fa'ata'ita'iga, totigilima, matatioata, ofu talaloa, ma isi).
- Taulima le mea faʻapipiʻi i se auala e aloese ai mai soʻo se lamatiaga e mafua mai i le manava, inu, poʻo le faʻafesoʻotaʻi.
I suʻesuʻega vailaʻau ma suʻesuʻega, e taua le faia o se galuega lelei o le pulega o le saogalemu o falesuesue ma faʻagaioi e tusa ai ma le taʻitaʻiga a tagata tomai faapitoa.
