Mawu Oyamba
5-bromo-3-cyanopyridine ndi organic pawiri ndi mankhwala chilinganizo C6H3BrN2. Ndi kristalo woyera mpaka wachikasu, wosungunuka mu zosungunulira zina monga ethanol ndi dimethyl sulfoxide. Zotsatirazi ndi kufotokozera mwatsatanetsatane za katundu, ntchito, kukonzekera ndi chitetezo zambiri za 5-bromo-3-cyanopyridine:
Chilengedwe:
-Maonekedwe: Makristalo oyera mpaka achikasu
-Posungunuka: pafupifupi 89-93°C
-Kuwira: pafupifupi 290-305 ° C
-Kuchulukana: Pafupifupi 1.64 g/mL
-Kulemera kwa mamolekyu: 174.01g/mol
Gwiritsani ntchito:
5-bromo-3-cyanopyridine nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe organic, ndipo ali zofunika ntchito m'minda ya kaphatikizidwe mankhwala, kaphatikizidwe mankhwala ndi kaphatikizidwe utoto.
Mapulogalamu apadera ndi awa:
- Pazamankhwala, zitha kugwiritsidwa ntchito popanga mankhwala odana ndi chotupa, ma antiviral ndi antibacterial mankhwala.
-Pa mankhwala ophera tizirombo, atha kugwiritsidwa ntchito popanga mankhwala ophera tizilombo komanso ophera udzu.
- Pankhani ya utoto, itha kugwiritsidwa ntchito kupanga utoto wachilengedwe.
Njira Yokonzekera:
Njira yokonzekera 5-bromo-3-cyanopyridine ikhoza kuchitidwa ndi izi:
1. 3-cyanopyridine amachitira ndi hydrobromic asidi pansi pa zinthu zamchere kupanga 5-bromo-3-cyanopyridine.
Zambiri Zachitetezo:
Njira zotsatirazi zodzitetezera ziyenera kutengedwa mukamagwiritsa ntchito 5-bromo-3-cyanopyridine:
-Ndi organic pawiri yomwe imakwiyitsa. Pewani kutulutsa fumbi kapena kukhudza khungu ndi maso.
-Pogwiritsa ntchito ndi kusunga, ayenera kutsatira njira zotetezera, kuvala zida zodzitetezera, monga magolovesi ndi magalasi oteteza chitetezo.
-Pewani kusakaniza kapena kukhudzana ndi zinthu monga ma oxidants amphamvu komanso ma acid amphamvu kuti mupewe zoopsa.
-Kusunga pamalo olowera mpweya kutali ndi moto woyaka komanso kutentha.
-Ukauzira kapena kukhudza khungu ndi maso, tsukani ndi madzi nthawi yomweyo. Funsani thandizo lachipatala ngati kuli kofunikira.
Poganizira zachitetezo, kugwiritsa ntchito ndi kusamalira 5-bromo-3-cyanopyridine kuyenera kutsata njira zolondola za labotale ndikutsata malamulo otetezedwa.
