Folasaga
2-Bromoisoniacin, lea e taʻua foʻi o le 2-bromopyridine-4-carboxylic acid, o se vailaʻau faʻapitoa. O lo'o ta'ua i lalo se folasaga i meatotino, fa'aoga, metotia sauniuni ma fa'amatalaga saogalemu o le 2-bromoisoniacinic acid:
Tulaga lelei:
- Fa'aaliga: 2-Bromoisoniacinic acid ose pa'epa'e pe pa'epa'e ma'a tioata.
- Solubility: E mafai ona faʻamavaeina i soʻo faʻaola pei ole vai, ethanol, ma eter.
- Mea tau vaila'au: E mafai ona o'o i le alkaline hydrolysis reactions i lalo o tulaga alkaline e maua ai fa'atasiga bromopyridine.
Fa'aaogā:
- E mafai foʻi ona faʻaaogaina e avea o se vali vaeluaga i le tuʻufaʻatasia o vali ma pigments.
Metotia:
- O se metotia masani sauniuni mo le 2-bromoisoniacinic acid e maua e ala i le taliina o le 2-picolinic acid ma le thionyl bromide. Faafefiloi le 2-picolinic acid ma le sulfoxide i totonu o se solu talafeagai ma faʻaopoopo i ai se faʻamaʻi faʻamaʻi. Ona fa'aopoopo lemu lea o le thionyl bromide, ona tupu ai lea o le tali. O le fofo tali sa togafitia lelei ma faʻamamaina ina ia maua ai se oloa 2-bromoisoniacinic acid ma maualuga le mama.
Fa'amatalaga o le Saogalemu: O se mea fa'aitaitagofie e ono fa'aoso ai le ita ma fa'aletonu pe a fa'afeso'ota'i ma le pa'u, mata, po'o le manava. E tatau ona ofuina ni mea e puipuia ai le tagata lava ia e pei o totigilima, mata tioata, ma talipupuni mata pe a fa'aaoga.
- Pe a tagofia le 2-bromoisoniacin, aloese mai le manavaina o lona pefu poʻo ausa. A mae'a togafitiga, e tatau ona fa'amama lelei vaega ma mea faigaluega.
- Le teuina lelei o le 2-bromoisoniacin, e tatau ona teuina i totonu o se nofoaga mago, malulu ma lelei-ventilated, ese mai le mumu ma oxidants. Teu ese ese mai mea mu, acids ma mea e fa'aitiitia ai.
- I le tulaga o le manava faʻafuaseʻi, faʻaalia i, poʻo le inuina o le 2-bromoisoniacin, saili vave togafitiga faafomaʻi ma aumai faʻatonuga poʻo le igoa ole oloa o loʻo fesiligia.
