| Tulaga lamatia | R36/37/38 – Fa'aitaita'i i mata, faiga manava ma le pa'u. R41 – Tulaga lamatia o le faaleagaina mata R37/38 – Fa'aitaita i le manava ma le pa'u. R22 – E afaina pe a foloina |
| Fa'amatalaga Saogalemu | S37/39 – Fai totigilima talafeagai ma le puipuiga o mata/mata S26 – Pe a pa'i i mata, fufulu vave i le tele o vai ma saili fautuaga fa'afoma'i. S39 – Fai le puipuiga o mata/mata. |
Folasaga
O le 2-Bromo-5-chloro-3-picoline o se fa'alapotopotoga fa'alenatura ma le fua fa'atatau kemikolo C7H6BrClN. O lo'o taua i lalo se fa'amatalaga o meatotino, fa'aoga, tapenaga ma fa'amatalaga saogalemu o le fa'aputuga:
natura:
-Fa'aaliga: 2-Bromo-5-chloro-3-picoline ose vai e leai se lanu po'o sina lanu samasama.
-Solubility: Solu i le tele o solvents organic, pei ole ethanol, dimethylformamide ma chloroform.
-O le mea faʻafefete ma le mea e faʻafefe ai: O le mea e faʻafefe ai le mea faʻapipiʻi e tusa ma le -35 ° C, ma le mea e faʻafefe ai e tusa ma le 205-210 ° C.
Fa'aaogā:
- 2-Bromo-5-chloro-3-picoline e mafai ona faʻaaogaina e fai ma mea amata poʻo le vaeluaga i le faʻaogaina o meaola, ma e mafai ona faʻaaogaina e faʻapipiʻi ai isi mea faʻapipiʻi, e pei o vailaau faʻasaina ma vailaʻau.
-O loʻo faʻaaogaina lautele foi i mea faʻapipiʻi, polychlorinated biphenyls, polybrominated biphenyls ma pigments.
Sauniuniga auala:
- 2-Bromo-5-chloro-3-picoline e masani ona saunia e le bromination ma le chlorination o le 3-picoline. Muamua, o le 3-methylpyridine e faʻafefe i le hydrogen bromide e maua ai le 2-bromo-5-methylpyridine, ona faʻafefe ai lea o le oloa ma se faʻamalosi chloride uʻamea e maua ai le oloa faʻatatau.
Fa'amatalaga Saogalemu:
- 2-Bromo-5-chloro-3-picoline e masani lava e le afaina tele i lalo ole fa'aoga masani. Peita'i, e ono fa'aita i mata, pa'u ma le manava, o lea e tatau ai ona fa'aeteete ina ia 'alofia le fa'afeso'ota'i sa'o.
-Fa'aoga ma mea faigaluega puipui talafeagai, e pei o totigilima vaila'au, mata tioata ma talipupuni mata.
-E tatau ona mulimulita'i faiga su'esu'e lelei a'o fa'aoga ma fa'atumauina lelei le ea.
- Aloese mai le faʻafesoʻotaʻi ma vailaʻau malolosi ma vailaʻau malosi i le taimi o le taulimaina ma le teuina.
