3-Bromo-5-chloropyridine-2-carboxylic acid (CAS # 1189513-50-5)
O le 3-Bromo-5-chloropicolinic acid o se mea faʻapipiʻi.
Tulaga lelei:
3-Bromo-5-chloro-2-pyridine carboxylic acid o se tioata e leai ni lanu faʻatasi ai ma mea faʻapitoa faʻatulagaina ma physicochemical. E malo i le vevela o le potu ma soluble i nisi solvents organic, e pei o le methanol, dimethylformamide, ma isi. O le tuufaatasiga e mautu i le ea ma e mafai ona feagai ma nisi o vailaau faʻamaʻi i lalo o nisi tulaga.
Talosaga: O lona fausaga faʻapitoa faʻapitoa e maua ai le tele o mea e mafai ona faʻaogaina.
Metotia:
O le auala masani mo le saunia o le 3-bromo-5-chloro-2-pyridine carboxylic acid e maua mai i le faʻaogaina o vailaʻau. Aemaise lava, e mafai ona amata mai le 2-pyrolinic acid poʻo le 2-pyridone, ma a maeʻa se faʻasologa o gaioiga, bromine ma chlorine atoms e mafai ona faʻafeiloaʻi e iu ai ina fausia le faʻapipiʻiina.
Fa'amatalaga Saogalemu:
Pe a faʻaaogaina le 3-bromo-5-chloro-2-pyridine carboxylic acid, e manaʻomia le mulimulitaʻia o faiga faʻaoga saogalemu. O se vaila'au lea ma o le pefu po'o le vaifofo e tatau ona 'alofia e ala i le inhalation. E tatau ona ofuina mea e puipui ai le tagata lava ia e pei o mata puipui, totigilima ma lavalava puipui a'o tagofia. O lo'o teuina ma lafoa'i le fa'aputuga e tusa ai ma tulafono fa'atatau ma lafoa'i lelei otaota.
