5-BROMO-2-HYDROXY-4-METHYLPYRIDINE（CAS# 164513-38-6) Folasaga
3. PH taua: E le faaituau po o sina acidic i le vai vaifofo.
4. Reactivity: O se electrophilic reagent lea e mafai ona auai i le tele o gaioiga faʻaola, e pei ole electrophilic substitution reactions, oxidation reactions, etc.
5. Faʻamautu: E mautu i le vevela o le potu, ae e mafai ona pala i lalo o le gaioiga o le vevela maualuga, faʻamaʻi poʻo le malosi malosi.
E iai le tele o fa'aoga i totonu o falesu'esu'e ma alamanuia, e aofia ai mea nei:
1. I le avea ai o se vailaʻau vailaʻau: e mafai ona faʻaaogaina e avea o se eletise eletise, Catalyst poʻo le faʻaitiitia o le sui i le faʻaogaina o meaola.
2. I le avea ai ma se faʻasao: Ona o ana mea faʻamaʻi, e mafai ona faʻaaogaina mo le saunia o mea faʻasao, e masani ona faʻaaogaina e puipuia ai fafie, ie, ma isi.
3. Vailaau Fa'afoma'i: e mafai ona fa'aogaina i le tu'ufa'atasiga o vaila'au po'o ni mea fa'alatalata mo nisi vaila'au.
O se auala masani e saunia ai se masima e ala i le tali atu i le 2-picoline ma le bromine. Laasaga faʻapitoa e mafai ona faasino i le auala lenei: Muamua, i lalo o tulaga talafeagai tali, 2-methylpyridine e tali atu i le bromine e maua ai le 5-bromo-2-methylpyridine. Ona, i lalo o tulaga alkaline, 5-bromo -2-methyl pyridine e togafitia i le sodium hydroxide e maua ai.
E tusa ai ma faʻamatalaga saogalemu, e tatau ona matauina mea nei pe a faʻaaoga pe faʻaaogaina le uʻamea:
1. Aloese mai le fa'afeso'ota'i sa'o ma le pa'u, mata, manava manava, ma isi mea. Fa'aaoga mea e puipuia ai le tagata lava ia e pei o totigilima, mata tioata ma matapulepule.
2. Taofi se si'osi'omaga e fa'alili lelei a'o fa'aoga ma 'alofia le manavaina o lona ausa.
3. E tatau ona tuʻu le teuina i totonu o se pusa faʻamaufaʻailoga, aloese mai le susulu o le la ma le maualuga o le vevela.
4. Afai na folo fa'afuase'i pe pa'i mai le pa'u, fufulu vave i le tele o vai ma saili fesoasoani fa'afoma'i ile taimi.
5. I le faʻaaogaina poʻo le lafoaia o le faʻalavelave, e tatau ona tausisia tulafono faʻalotoifale ma tulafono faatonutonu ma taualumaga saogalemu.
