2,3-Dibromopyridine (CAS# 13534-89-9) sumo

2,3-dibromopyridine is organic compound. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira, uye ruzivo rwekuchengetedza:
nature:
-2,3-dibromopyridine iruvara rweyero isina ruvara uye ine hwema hunonhuwa.
-Iyo inonyungudika mune organic solvents senge ethanol, dimethylformamide, uye dichloromethane pakushambidzika kwekamuri, asi isina kunyungudika mumvura.
-Komboni iyi inonzwa kuchiedza nemhepo uye inofanirwa kuchengetwa mumudziyo wakavharwa kure nechiedza.
Chinangwa:
-2,3-dibromopyridine inowanzoshandiswa sechinhu chakakosha chepakati mune organic synthesis.
-Inogona kushandiswa kutsiva uye condensation maitiro mune organic synthesis.
Kugadzira nzira:
-Nzira yakajairika yekugadzirira 2,3-dibromopyridine iri kuburikidza nebromination reaction yepyridine.
-Iyo inowanzoshandiswa nzira yekugadzirira ndeyekupisa pyridine mumvura yakadzika yebromine kuti iite, uye inoguma 2,3-dibromopyridine inopera kubva mumhinduro yekugadzirisa mushure mekutonhora.
Chekuchengetedza ruzivo:
-2,3-dibromopyridine chinhu chinogumbura chinogona kukonzera kutsamwa kwemaziso uye ganda paunosangana.
-Midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi, uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa panguva yekushanda.
-Dzivisa kufema guruva rayo kana gasi, uye shanda munzvimbo ine mhepo inofefetera.
