Folasaga
2-Hydroxy-3-nitro-6-methylpyridine o se faʻalapotopotoga faʻapitoa faʻatasi ai ma le vailaʻau C7H7N2O3. O lo'o i lalo se fa'amatalaga auiliili o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:
natura:
-Fa'aaliga: 2-hydroxy-3-nitro-6-methylpyridine o se paʻepaʻe e paʻepaʻe lanu samasama samasama paʻu.
-Solubility: o lona solubility i le vai e maualalo, soluble i le tele o solvents organic pei o le ava malosi, eter, ketone, ma isi.
-Melting point: O le liusuavai o lenei tuufaatasiga e tusa ma le 194-198 °C.
-Stability: mautu i le vevela o le potu, ae tatau ona aloese mai le faʻaalia i le malamalama ma le maualuga o le vevela siosiomaga.
Fa'aaogā:
-2-hydroxy-3-nitro-6-methylpyridine e masani ona faʻaaogaina e avea o se vaeluagalemu i le faʻaogaina o meaola ma faʻaaogaina i le tuʻufaʻatasia o isi mea faʻapipiʻi.
-E mafai foʻi ona faʻaaogaina i le sauniuniga o fesoasoani faʻapipiʻi paʻu, vailaau faʻasaina, vailaʻau ma vali ma isi fanua.
Metotia:
-2-Hydroxy-3-nitro-6-methylpyridine e masani ona maua e ala i vailaʻau faʻasolosolo. O le auala patino e mafai ona maua e ala i le tali atu i le 3-methylpyridine faʻatasi ma le nitric acid e ala i le faʻafefeteina o le faʻafefe, ona faʻaitiitia ai lea ma le faʻaogaina o le hydroxylation.
Fa'amatalaga Saogalemu:
-2-hydroxy-3-nitro-6-methylpyridine o se vailaʻau faʻapitoa e iai ni oona. Mulimuli i ta'iala saogalemu ile falesu'esu'e ile taimi ole fa'agaioiga.
-O le fa'afeso'ota'i po'o le fa'auluina o lenei vaila'au e ono mafua ai le ita ma manu'a i le tino o le tagata. E tatau ona 'alofia le fa'afeso'ota'i o le pa'u, inhalation ma le ingestion. O totigilima fa'apolofesa fa'apolofesa, mata ma mea e manava e tatau ona ofuina a'o fa'aoga.
- I le tulaga e pa'i ai i le pa'u po'o mata, fufulu vave i le tele o vai ma saili fautuaga fa'afoma'i i se taimi vave e mafai ai.
-E tatau ona teuina le mea faʻapipiʻi i totonu o se nofoaga faʻamaufaʻailogaina, mago, lelei-ventilated, ese mai afi ma oxidizing agents. Pe a lafoa'i otaota, mulimuli i tulafono fa'alotoifale puipuia o le siosiomaga.
