Gabatarwa
3-Chloro-2-hydroxy-5- (trifluoromethyl) pyridine fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga yanayinsa, amfaninsa, hanyoyin masana'anta da bayanan aminci:
1. Hali:
- Bayyanar: 3-Chloro-2-hydroxy-5- (trifluoromethyl) pyridine mara launi ne zuwa kodadde rawaya mai ƙarfi.
- Solubility: Yana kusan rashin narkewa a cikin ruwa, amma yana narkewa a cikin kaushi na halitta kamar ether, methanol da methylene chloride.
- Sinadarai: Yana da wani fili na alkaline wanda ke yin maganin neutralizing da acid. Hakanan za'a iya amfani dashi azaman reagent na fluorine don gabatar da ƙungiyoyin trifluoromethyl cikin wasu mahaɗan kwayoyin halitta.
2. Amfani:
- 3-Chloro-2-hydroxy-5- (trifluoromethyl) pyridine yawanci ana amfani dashi a cikin halayen halayen kwayoyin halitta azaman mai kara kuzari ko reagent. Misali, ana iya amfani da shi don gina haɗin gwiwar carbon-fluorine da halayen amination.
- Hakanan za'a iya amfani dashi azaman kayan farawa ko tsaka-tsaki a cikin haɗin gwari.
3. Hanya:
- Hanyar shiri da aka saba amfani da ita shine amsa pyridine tare da trifluoroformic acid da sulfuric acid don samar da 3-chloro-2-hydroxy-5- (trifluoromethyl) pyridine.
4. Bayanin Tsaro:
