2-Chloro-3-bromo-4-methylpyridine（CAS# 55404-31-4)

Folasaga

O se fa'aputu fa'aola fa'atasi ai ma se fuala'au kemikolo o le C6H5BrClN ma le mamafa mole mole o le 192.48g/mol. O lo'o i lalo se fa'amatalaga o lona natura, fa'aoga, fa'atulagaina ma fa'amatalaga saogalemu:

1. natura:

- Fa'aaliga: leai se lanu i le vai samasama malamalama po'o le malo;

-Puna: e uiga i le 220-222 ℃ (i le barometer);

-mea liusuavai: e uiga i 33-35 ℃;

- Ma'ale'ale i le malamalama, aloese mai le fa'aumiumi o le la;

-Solu i solu masani masani e pei ole ethanol ma dimethylformamide.

2. fa'aoga:

-I le avea ai o se vaeluagalemu: e mafai ona faʻaaogaina e saunia ai isi mea faʻapipiʻi, e pei o mea faʻapipiʻi o loʻo i ai le fluorine poʻo mea e maua mai i isi vailaʻau heterocyclic;

- Faʻaaogaina i le faʻaogaina o meaola: E mafai ona faʻaaogaina e avea o se reagent taua i le faʻaogaina o meaola e faʻafeiloaʻi ai vaega galue e pei o halogen atoms poʻo vaega amino.

3. Sauniuniga auala:

-E masani lava ona saunia e se tuufaatasiga o chlorination, bromination ma methylation o pyridine.

4. Fa'amatalaga Saogalemu:

-o se fa'alapotopotoga fa'aola, e ono lamatia;

-e tatau ona tusa ai ma taualumaga o le saogalemu o vailaʻau mo le gaioiga, e aloese ai mai le faʻafesoʻotaʻi saʻo ma le paʻu ma mata;

-E tatau ona tuʻuina atu le faʻaleleia lelei i le taimi o le faʻaaogaina e aloese ai mai le manavaina o ausa;

-Ia tia'i otaota, ia usita'ia tulafono fa'alotoifale.
