5-Bromo-4-methyl-pyridine-2-carboxylic acid (CAS# 886365-02-2)

Mawu Oyamba

Ndi organic pawiri yomwe mankhwala ake ndi C7H6BrNO2.

Makhalidwe a kompani ndi awa:

-Maonekedwe: Opanda utoto mpaka kristalo wachikasu kapena ufa

-Kusungunuka: 63-66°C

-Kuwira: 250-252°C

-Kuchulukana: 1.65g/cm3

Nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati pakupanga zinthu zina zamagulu. Lili ndi ntchito zofunika pazamankhwala ndipo lingagwiritsidwe ntchito popanga mankhwala a mamolekyu ena a mankhwala. Komanso, ndi kupanga wapakatikati kwa kwambiri ogwira antibacterial wothandizira. Zina zomwe zingagwiritsidwe ntchito ndi monga zopangira zinthu, utoto wa photosensitizing, ndi mankhwala ophera tizilombo.

Njira kukonzekera pyridine makamaka zochokera bromination wa 4-methylpyridine ndi sodium cyanide mu 5-bromo-4-methylpyridine, ndiyeno anachita ndi rhenium trioxide mu dichloromethane kupanga chandamale mankhwala.

Ponena za chitetezo, ili ndi kawopsedwe kena komanso kukwiya. Chonde samalani ndi zinthu zotsatirazi mukamagwiritsa ntchito:

-Pewani kupuma fumbi, utsi ndi mpweya kuti musakhudze khungu ndi maso.

-Valani zida zoyenera zodzitetezera panthawi yomwe mukugwiritsa ntchito, monga magalasi oteteza mankhwala, magolovesi oteteza komanso masks oteteza.

-Ayenera kugwiritsidwa ntchito pamalo abwino mpweya wabwino komanso kukhala aukhondo kuntchito.

-Kusungirako kuyenera kusungidwa pamalo ouma, ozizira, kutali ndi moto ndi oxidizing agents.

Mukamagwiritsa ntchito zitsulo, chonde tsatirani ndondomeko yoyenera yachitetezo ndi malamulo, ndikuwunika zoopsa zake ndi zoopsa zomwe zingatheke malinga ndi momwe zilili.
