3 5-Dibromo-2-methylpyridine （CAS # 38749-87-0)

Intangiriro

3,5-Dibromo-2-methylpyriridine ni ifumbire mvaruganda ifite imiti ya C6H5Br2N. Imiterere nuko imyanya 2 na 6 kumpeta ya pyridine isimburwa na methyl na atome ya bromine.

Kamere:

3,5-Dibromo-2-methylpyriridine ni ibara ritagira ibara ryijimye ry'umuhondo wijimye kandi ufite impumuro nziza. Nibikomeye mubushyuhe bwicyumba kandi bifite ubushobozi buke. Ifite aho gushonga ya 56-58 ° C hamwe na 230-232 ° C.

Koresha:

3,5-Dibromo-2-methylpyriridine ikoreshwa cyane muri synthesis. Irashobora gukoreshwa nka reagent muguhuza ibice bitandukanye kama, nkibiyobyabwenge, imiti yica udukoko n amarangi. Mubyongeyeho, irashobora kandi gukoreshwa nkibikoresho bifatika mu gusesengura imiti.

Uburyo bwo Gutegura:

Uburyo bwo gutegura 3,5-Dibromo-2-methylpyriridine mubusanzwe bikorwa na alkylation reaction na bromination reaction ya pyridine. Ubwa mbere, imyanya 2 muri pyridine methylated hamwe na methylating agent mubihe byibanze kugirango ikore 2-picoline. Noneho, 2-methylpyridine isubizwa hamwe na bromine kugirango itange ibicuruzwa byanyuma 3,5-Dibromo-2-methylpyridine.

Amakuru yumutekano:

3,5-Dibromo-2-methylpyridine irakaze kandi yangirika kandi itaziguye guhura nuruhu, amaso hamwe nuduce twinshi. Mugihe cyo gukoresha, hagomba gufatwa ingamba zo kurinda umuntu ku giti cye, nko kwambara ibirahuri bikingira hamwe na gants, no kureba ko icyo gikorwa gikorerwa ahantu hafite umwuka mwiza. Byongeye kandi, nikintu cyaka kandi kigomba kubikwa kure yumuriro nubushyuhe bwo hejuru. Niba ushizemo umwuka cyangwa winjiye mu makosa, ugomba kwivuza mugihe gikwiye.
