5-BROMO-2-HYDROXY-4-METHYLPYRIDINE (CAS# 164513-38-6)

Ndi organic pawiri ndi mankhwala chilinganizo C8H8BrNO. Lili ndi zotsatirazi: 1. Maonekedwe: Ndi olimba opanda mtundu kapena opepuka achikasu.2. Kusungunuka: Imatha kusungunuka pang'ono m'madzi ndipo imasungunuka mosavuta mu zosungunulira za organic monga ethanol ndi dimethyl sulfoxide.

3. Phindu la PH: Sililowerera kapena kuti acidic pang'ono munjira yamadzi.

4. Reactivity: Ndi electrophilic reagent yomwe imatha kutenga nawo mbali pazochita zambiri za organic, monga electrophilic substitution reactions, ma oxidation reaction, etc.

5. Kukhazikika: Imakhala yokhazikika kutentha, koma imatha kuwonongeka chifukwa cha kutentha kwakukulu, okosijeni kapena asidi amphamvu.

Ili ndi ntchito zosiyanasiyana mu labotale ndi mafakitale, kuphatikiza izi:

1. Monga mankhwala opangira mankhwala: angagwiritsidwe ntchito ngati electrophilic reagent, Catalyst kapena kuchepetsa wothandizira mu organic synthesis.

2. Monga chosungira: Chifukwa cha antibacterial katundu, angagwiritsidwe ntchito pokonzekera zotetezera, zomwe zimagwiritsidwa ntchito nthawi zambiri kuteteza nkhuni, nsalu, ndi zina zotero.

3. Medicine munda: angagwiritsidwe ntchito synthesis mankhwala kapena intermediates mankhwala ena.

Njira yodziwika bwino yopangira mchere ndikuchita 2-picoline ndi bromine. Masitepe enieni angatanthauze njira zotsatirazi: Choyamba, pansi pa zochitika zoyenera, 2-methylpyridine imachitidwa ndi bromine kuti ipeze 5-bromo-2-methylpyridine. Ndiye, pansi pa zinthu zamchere, 5-bromo -2-methyl pyridine amathandizidwa ndi sodium hydroxide kuti apeze.

Ponena za chitetezo, zotsatirazi ziyenera kuzindikirika mukamagwiritsa ntchito kapena pogwira chitsulo:

1. Pewani kukhudzana mwachindunji ndi khungu, maso, kupuma, ndi zina zotero. Valani zida zoyenera zodzitetezera monga magolovesi, magalasi ndi masks.

2. Sungani malo olowera mpweya wabwino mukamagwiritsa ntchito ndipo pewani kutulutsa mpweya wake.

3. Kusungirako kumayenera kuikidwa mu chidebe chosindikizidwa, kupewa kuwala kwa dzuwa ndi kutentha kwakukulu.

4. Ngati mwamezedwa mwangozi kapena kukhudza khungu, sukani mwamsanga ndi madzi ambiri ndipo funsani thandizo lachipatala nthawi yake.

5. Pokagwiritsa ntchito kapena kutaya malo, akuyenera kutsatira malamulo a m'deralo ndi ndondomeko za chitetezo.
