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

Mawu Oyamba

3,5-Dibromo-2-methylpyriridine ndi mankhwala opangidwa ndi mankhwala a C6H5Br2N. Kapangidwe kake ndikuti malo a 2 ndi 6 pa mphete ya pyridine amasinthidwa ndi maatomu a methyl ndi bromine, motsatana.

Chilengedwe:

3,5-Dibromo-2-methylpyriridine ndi kristalo wopanda mtundu wotuwa wachikasu wokhala ndi fungo loyipa. Ndi cholimba kutentha kutentha ndipo chimakhala ndi kusungunuka kwapakatikati. Ili ndi malo osungunuka a 56-58 ° C ndi malo otentha a 230-232 ° C.

Gwiritsani ntchito:

3,5-Dibromo-2-methylpyriridine imagwiritsidwa ntchito kwambiri popanga organic synthesis. Itha kugwiritsidwa ntchito ngati reagent mu kaphatikizidwe kamitundu yosiyanasiyana ya organic, monga mankhwala, mankhwala ophera tizilombo ndi utoto. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati cholembera pakusanthula kwamankhwala.

Njira Yokonzekera:

Njira yokonzekera 3,5-Dibromo-2-methylpyriridine nthawi zambiri imachitika ndi alkylation reaction ndi bromination reaction ya pyridine. Choyamba, malo a 2 mu pyridine ndi methylated ndi methylating agent pansi pa zofunikira kuti apange 2-picoline. Kenako, 2-methylpyridine imachitidwa ndi bromine kuti ipereke chomaliza 3,5-Dibromo-2-methylpyridine.

Zambiri Zachitetezo:

3,5-Dibromo-2-methylpyridine imakwiyitsa komanso yowononga komanso yokhudzana ndi khungu, maso ndi mucous nembanemba ziyenera kupewedwa. Mukamagwiritsa ntchito, muyenera kutsata njira zodzitetezera, monga kuvala magalasi oteteza ndi magolovesi, ndikuwonetsetsa kuti opaleshoniyo ikuchitika pamalo abwino mpweya wabwino. Kuonjezera apo, ndi chinthu choyaka moto ndipo chiyenera kusungidwa kutali ndi moto wotseguka komanso malo otentha kwambiri. Ngati mutakokedwa kapena kulowetsedwa molakwika, muyenera kupita kuchipatala munthawi yake.
