5-Bromo-2-methoxy-4-methylpyridine (CAS# 164513-39-7) isingeniso
I-2-Methoxy-4-methyl-5-bromopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-2-Methoxy-4-methyl-5-bromopyridine iqinile enamakristalu amhlophe kuya kokuphuzi okuphaphathekile anephunga elingavamile.
Sebenzisa:
I-2-Methoxy-4-methyl-5-bromopyridine i-reagent evame ukusetshenziswa ku-organic synthesis. Ivamise ukusetshenziswa ekuphenduleni kwe-catalytic ku-organic synthesis efana ne-Suzuki-Miyaura reaction, Heck reaction, njll.
Indlela:
Indlela yokulungiselela i-2-methoxy-4-methyl-5-bromopyridine ngokuvamile ifinyelelwa nge-halogenation kanye nokusabela esikhundleni se-pyridine. Ngokuqondile, i-pyridine notshwala kungasabela ukuze kulungiswe i-2-methoxy-4-methylpyridine, bese i-brominated ukuthola umkhiqizo ohlosiwe.
Ulwazi Lokuphepha:
I-2-Methoxy-4-methyl-5-bromopyridine kufanele igcinwe esitsheni esivaliwe ukugwema ukuthintana nomoya kanye nomswakama. Ngesikhathi sokusetshenziswa, ukunakekelwa kufanele kuthathwe izinyathelo zokuzivikela, njengokugqoka amagilavu nezibuko. Gwema ukuhogela, ukukungenisa, noma ukuthintana nesikhumba. Kufanele kuqashelwe ukusetshenziswa kwemishini yokukhipha umoya ngesikhathi sokuphatha noma sokusebenza, futhi kufanele kuqashelwe izinqubo ezifanele zokusebenza zokuphepha. Uma ukuhogela, ukumunca, noma ukuthinta isikhumba, funa usizo lwezokwelapha ngokushesha.
