-Matsayin narkewa: Matsayinsa na narkewa shine 90-93 ° C.
-Solubility: 2 (1H) -Pyridinone,3-bromo-5- (trifluoromethyl) - yana da wasu solubility a cikin abubuwan da ake amfani da su na yau da kullum, irin su ethanol, ether da chloroform.
Amfani:
-Chemical bincike: 2 (1H) -Pyridinone,3-bromo-5- (trifluoromethyl) - za a iya amfani da a matsayin reagent ko matsakaici a cikin kwayoyin kira. Ana amfani da shi sau da yawa don gina kwarangwal na hadadden kwayoyin halitta a cikin halayen ƙarfe-catalyzed.
-Haɓaka miyagun ƙwayoyi: Saboda tsarinsa na musamman da sinadarai, yana iya taka muhimmiyar rawa wajen haɓaka magunguna, kamar maganin cutar kansa, magungunan rigakafi, da sauransu.
Hanyar Shiri:
2 (1H) -Pyridinone, 3-bromo-5- (trifluoromethyl) - ana iya haɗa shi ta hanyoyi daban-daban, mai zuwa yana ɗaya daga cikin hanyoyin haɗin gwiwar gama gari:
2-hydroxyl pyridine yana amsawa tare da magnesium bromide don samar da 2-hydroxyl -3-bromopyridine. An yi amfani da 3-bromopyridine tare da fluoromethyllithium don ba da 2 (1H) -Pyridinone, 3-bromo-5- (trifluoromethyl) -. Gabaɗaya ana yin haɗin haɗin a cikin kaushi mai ƙarfi, kamar dimethyl sulfoxide, kuma a ƙananan yanayin zafi.
Bayanin Tsaro: Tsaro na
- 2 (1H) - Pyridinone, 3-bromo-5- (trifluoromethyl) - ba a riga an kimanta shi ba, don haka ya kamata a kula da kulawa lokacin sarrafawa da adanawa. An shawarci masu amfani da su sanya kayan kariya masu dacewa, kamar safofin hannu na lab da kariyar ido. Ka guji shakar ƙurarsa ko tuntuɓar fata.
-Saboda abubuwan sinadaransa, yana iya zama mai guba ga muhallin ruwa. Da fatan za a bi ƙa'idodin aminci masu dacewa yayin amfani, don guje wa fitarwa zuwa cikin ruwa.
-Lokacin da ake amfani da wannan fili, ana ba da shawarar yin aiki a ƙarƙashin ingantattun yanayin dakin gwaje-gwaje don guje wa shakar gurɓataccensa. Idan zubewar bazata ko numfashi, nemi kulawar likita nan da nan.
