Shandisa:

- 3-Bromo-5-methyl-pyridine inowanzoshandiswa sepakati mune organic synthesis uye inogona kushandiswa kugadzirira mamwe maitiro ehupenyu, akadai semishonga, mishonga yezvipembenene uye dhayi.

-Iyo inogona zvakare kushandiswa se reagent mukutsvaga uye murabhoritari.

 

Kugadzirira nzira:

- 3-Bromo-5-methyl-pyridine inogona kugadzirwa nenzira dzakasiyana-siyana, imwe yadzo inowanzoshandiswa nekuwedzera methylating agent (yakadai semethyl magnesium bromide) ku3-bromopyridine.

 

Zvekuchengetedza

- 3-Bromo-5-methyl-pyridine inofanira kushandiswa maererano nemaitiro akakodzera ekuchengetedza, zvakadai sekupfeka zvidziviriro zvemunhu zvinodiwa mumarabhoritari emakemikari.

-Inogona kukonzera kutsamwa uye kukuvadza kwemaziso, ganda uye kufema system. Chenesa nzvimbo yabatwa nekukasika uye tsvaga rubatsiro rwekuchipatara kana zvichidiwa.

-Paunenge uchichengetedza uye uchibata, inofanira kuchengetwa mumudziyo wakavharwa, kure nemoto uye kupisa kwakanyanya.

-Paunenge uchirasa tsvina, teerera mitemo yemunharaunda uye tora matanho akakodzera ekudzivirira kwezvakatipoteredza.
