Folasaga
3-bromo-4-methoxypyridine o se faʻalapotopotoga faʻapitoa ma se vailaʻau faʻasolosolo o le C6H6BrNO ma le mamafa mole o le 188.03. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:
natura:
1. Fa'aaliga: 3-bromo-4-methoxypyridine o se lanu samasama i le samasama mumu.
2. solubility: soluble i solu organic pei ole eter ma chlorinated hydrocarbons, le mafai ona solu i le vai.
3. liusuavai: e uiga i 50-53 ℃.
4. mamafa: e uiga i 1.54 g/cm.
Fa'aaogā:
O le 3-bromo-4-methoxypyridine o se mea taua tele o le faʻaogaina o meaola, e masani ona faʻaaogaina i le tuʻufaʻatasia o vailaau faʻasaina, vailaʻau ma isi mea faʻapipiʻi. O lo'o i ai le tele o fa'aoga i le matata o su'esu'ega kemisi ma vaila'au.
Sauniuniga auala:
3-bromo-4-methoxypyridine e masani ona faʻapipiʻiina i laasaga nei:
1. O le 2-bromo-5-nitropyridine e tali atu i le methanol e maua ai le 2-methoxy-5-nitropyridine.
2. 2-methoxy-5-nitropyridine e tali atu i le cuprous bromide saunia i le sulfuric acid e maua ai le 3-bromo-4-methoxypyridine.
Fa'amatalaga Saogalemu:
1. 3-bromo-4-methoxypyridine e faʻafefe ma e tatau ona aloese mai le faʻafesoʻotaʻi ma le paʻu, mata ma le manava.
2. i le tagofiaina ma le fa'aogaina, e tatau ona fa'aofuina mea e puipuia ai le tagata lava ia, e pei o totigilima ma matatioata puipui.
3. O le teuina e tatau ona taofia le faʻafesoʻotaʻi ma vailaʻau faʻamaʻi ma vailaʻau malolosi, ma faʻamaufaʻailoga le pusa.
4. I lalo o le faʻaoga talafeagai ma le teuina o tulaga, 3-bromo-4-methoxypyridine o se vailaʻau vailaʻau saogalemu, ae e manaʻomia lava ona faʻagaioia ma le faʻaeteete.
