5-Bromo-2-methyl-3-nitropyridine (CAS# 911434-05-4)

Mawu Oyamba

5-Bromo-2-methyl-3-nitropyridine ndi organic pawiri.

Katundu: 5-Bromo-2-methyl-3-nitropyridine ndi kristalo wachikasu mpaka lalanje wokhala ndi kukoma kwapadera kwa nitro. Ndiwokhazikika kutentha kwa firiji, koma kuwonongeka kumatha kuchitika mukatenthedwa kapena kukhudzana ndi ma asidi amphamvu.

Itha kugwiritsidwanso ntchito pakuwunika kwamankhwala, ma biomarkers, ndi organic synthesis.

Njira yokonzekera: Njira yokonzekera 5-bromo-2-methyl-3-nitropyridine ikhoza kukhala nitrification. Njira yodziwika bwino ndikuchita 2-methylpyridine yokhala ndi nitric acid kuti ipange 2-methyl-3-nitropyridine, ndiyeno gwiritsani ntchito bromine kuti iwonongeke pamaso pa sulfuric acid kuti mupeze chomaliza.

Zambiri zachitetezo: 5-bromo-2-methyl-3-nitropyridine ndizokhazikika pakagwiritsidwe ntchito wamba, komabe ndikofunikira kulabadira ntchito yotetezeka. Ndi chinthu choyaka ndipo kukhudzana ndi malawi otseguka kapena kutentha kwakukulu kuyenera kupewedwa. Zida zodzitetezera zoyenerera, monga magolovesi a mu labotale ndi magalasi oteteza chitetezo, ziyenera kuvalidwa pogwira ntchito ndi kupewa kukhudzana ndi khungu ndi maso. Mukakhudzana mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala mwamsanga. Zinyalala ziyenera kusungidwa bwino ndikutayidwa kuti ziteteze chilengedwe.
