Intangiriro
3-bromo-4-mikorerexypyridine ni ifumbire mvaruganda ifite imiti ya C6H6BrNO nuburemere bwa molekile ya 188.03. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
1. Kugaragara: 3-bromo-4-mikorerexypyridine ni umuhondo woroshye kugeza umuhondo ukomeye.
2. Gukemura: gushonga mumashanyarazi kama nka ether na hydrocarbone ya chlorine, idashonga mumazi.
3. Gushonga ingingo: hafi 50-53 ℃.
4. Ubucucike: hafi 1.54 g / cm.
Koresha:
3-bromo-4-mikorerexypyridine ningirakamaro yingirakamaro ya synthesis hagati, ikunze gukoreshwa muguhuza imiti yica udukoko, imiti nibindi bintu kama. Ifite uburyo butandukanye bwo gukoresha mubushakashatsi bwubushakashatsi nubuvuzi.
Uburyo bwo Gutegura:
3-bromo-4-mikorerexypyridine muri rusange ihuzwa nintambwe zikurikira:
1. 2-bromo-5-nitropyridine ikoreshwa na methanol kugirango ibone 2-mikorerexy-5-nitropyridine.
2.
Amakuru yumutekano:
1. 3-bromo-4-mikorerexypyridine irakaze kandi igomba kwirinda guhura nuruhu, amaso hamwe nubuhumekero.
2. Mugukoresha no gukoresha, bigomba kwambara ibikoresho byabigenewe bikingira, nka gants hamwe nikirahure kirinda.
3. Ububiko bugomba kubuza guhura na okiside na acide zikomeye, kandi bigakomeza gufunga ikintu.
