Folasaga
3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
1. Natura:
- Fa'aaliga: 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine e leai se lanu i se lanu samasama mumu.
- Solubility: E toetoe lava a le mafai ona solu i le vai, ae soluble i solu faʻaola pei ole eter, methanol ma methylene chloride.
- O mea tau vaila'au: O se fa'aputuga alkaline e fa'atino ai se fa'a'ese'esega fa'asaga i vaila'au. E mafai foʻi ona faʻaaogaina e fai ma faʻaulu faʻafefete e faʻafeiloaʻi vaega trifluoromethyl i isi faʻalapotopotoga faʻapitoa.
2. Fa'aoga:
- 3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine e masani ona faʻaaogaina i faʻasologa faʻasologa o meaola e pei o se faʻamalosi poʻo se reagent. Mo se faʻataʻitaʻiga, e mafai ona faʻaaogaina e fausia ai fusi carbon-fluorine ma tali amination.
- E mafai foʻi ona faʻaaogaina e fai ma mea amata poʻo se mea faʻapitoa i le faʻaogaina o vailaau faʻasaina.
3. Metotia:
- O se auala e masani ona fa'aaogaina o le fa'aogaina o le pyridine ma le trifluoroformic acid ma le sulfuric acid e maua ai le 3-chloro-2-hydroxy-5-(trifluoromethyl)pyridine.
4. Fa'amatalaga Saogalemu:
- 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine e tatau ona aloese mai le taimi o le teuina ma faʻaoga i le faʻafesoʻotaʻi ma vailaʻau malolosi ma mea faʻafefe e aloese ai mai le afi poʻo le pa.
- Atonu e i ai se aafiaga ita i le pa'u, mata, ma le manava, ma e tatau ona ofuina meafaigaluega puipuia talafeagai e pei o totigilima, mata tioata, ma mea e puipuia ai le manava pe a faagaoioi.
- Pe a faʻaaogaina poʻo le tagofiaina o le vailaʻau, e tatau ona faia i totonu o se nofoaga e faʻafefe lelei ma aloese mai le manava poʻo le faʻalavelave faʻafuaseʻi. A maeʻa togafitiga, e tatau ona faʻamamaina lelei le vaega ua afaina.
