Folasaga

5-Bromo-2-methoxy-4-methyl-3-nitropyridine o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:

 

Tulaga lelei:

- Fa'aaliga: Malosi le lanu

- Solubility: Solu i nisi vaifofo organic, pei ole ethanol ma dimethylformamide

- Mausalī: E mautu i le vevela o le potu, ae e mafai ona pala i le malamalama susulu

 

Fa'aoga: E fa'aaogaina lautele i le falema'i ma fa'ato'aga.

- Su'esu'ega fa'asaienisi: e avea o se mea'ai po'o se mea fa'afofoga mo fa'agaioiga fa'aola, e fa'aaogaina fo'i i su'esu'ega ma atina'e kemisi fa'aola.

 

Metotia:

O le sauniuniga o le 5-bromo-2-methoxy-4-methyl-3-nitropyridine e mafai ona faʻataunuʻuina e ala i se faʻasologa o vailaʻau faʻasolosolo, e aofia ai nisi o laasaga faʻasolosolo faʻavae, e pei o le sui ma le faʻamaʻiina.

 

Fa'amatalaga Saogalemu:

- O se organobromine ma e mafai ona ita ma oona. O faiga e puipuia ai le tagata lava ia, e pei o le ofuina o mata puipui ma totigilima, e tatau ona faia i le taimi o le taotoga.

- E tatau ona usita'i le lafoa'iina o otaota ma tulafono fa'alotoifale e lafoa'i ai otaota e 'alofia ai a'afiaga leaga o le si'osi'omaga.

- E tatau ona 'alo'ese mea e fa'amumu ai pe a teu ma fa'aoga ona e ono mu.
