Folasaga
2-Chloro-3-amino-5-bromopyridine o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga puupuu i lona natura, faʻaoga, auala gaosiga ma faʻamatalaga saogalemu:
Tulaga lelei:
- Fa'aaliga: Pa'epa'e i tioata samasama samasama
- Soluble: Solu i le chloroform ma ethanol, solubility teisi i le vai
Fa'aaogā:
- E mafai foʻi ona faʻaogaina le faʻapipiʻi e fai ma faʻamalosi i le faʻaogaina o meaola ma e iai sona sao taua i le faʻaogaina o isi mea faʻapitoa.
Metotia:
- O le tuʻufaʻatasiga o le 2-chloro-3-amino-5-bromopyridine e masani ona faʻatinoina e faʻaaoga ai le faʻaogaina o le chlorination-bromination. E saunia e ala i le tali atu i le 3-amino-4-bromopyridine ma chlorinating agents (e pei o le phosphorus trichloride, sulfuryl chloride, ma isi).
Fa'amatalaga Saogalemu:
- 2-Chloro-3-amino-5-bromopyridine ose vailaʻau ma e manaʻomia ni puipuiga talafeagai e pei o le ofuina o totigilima vailaʻau ma matapulepule.
- Pe a faʻaaogaina ma teuina, faʻafesoʻotaʻi ma vailaʻau faʻamaʻi, malosi malosi, ma alkali malosi e tatau ona aloese mai le faʻalavelave mataʻutia.
- E mafai ona avea ma vailaʻau e malosi i le paʻu, mata, ma le manava, ma e tatau ona fufulu i le vai i le taimi lava e faʻafesoʻotaʻi ai ma e tatau ona sailia togafitiga faafomaʻi.
