Folasaga
2,5-Dibromo-4-methylpyridine o se faʻalapotopotoga faʻapitoa. O lo'o taua i lalo se fa'amatalaga auiliili i meatotino, fa'aoga, metotia sauniuni ma fa'amatalaga saogalemu o lenei fa'apotopotoga:
Tulaga lelei:
2,5-Dibromo-4-methylpyridine o se mea mautu e leai se lanu i foliga tioata samasama. E malosi le solubility ma e soluble i le tele o solvents organic. Ose fa'aputuga le mautu e malepe gofie i le la.
Fa'aaogā:
O lenei tuufaatasiga e masani ona faʻaaogaina e avea o se mea mataʻutia ma reagent i le faʻaogaina o meaola.
Metotia:
2,5-Dibromo-4-methylpyridine e masani ona saunia e ala i le tali atu o le p-toluene ma le pyridine brominated. O le P-toluene e tali atu i le cuprous bromide e fausia ai le 2-bromotoluene, ona fa'afeagai ai lea ma le pyridine i lalo ole fa'ama'i fa'ama'i e maua ai se oloa mulimuli.
Fa'amatalaga Saogalemu:
2,5-Dibromo-4-methylpyridine e manaʻomia ona taulimaina ma le faʻaeteete ona o se vailaʻau oona. E tatau ona faʻaeteete ina ia aloese mai le faʻafesoʻotaʻi ma le paʻu, mata, ma le manava ile taimi ole taotoga. E tatau ona ofuina ni mea e puipui ai le tagata lava ia e pei o totigilima, mata puipui, ma matapulepule pe a fa'aoga i totonu o le falesu'esu'e. Pe a teuina ma taulimaina, e tatau ona taofia mai mea e mu ma mea e faʻamaʻi ai. Afai e foloina le vaila'au pe manavaina i se mea sese, e tatau ona vave sailia togafitiga faafomaʻi. A lafoa'i otaota, e tatau ona mulimulita'i tulafono fa'alotoifale ma lafoa'i lelei otaota ina ia 'alofia ai le fa'aleagaina o le si'osi'omaga.
