Isingeniso
I-methyl-2-bromoisonicotinate iyinhlanganisela ye-organic enefomula yamakhemikhali i-C8H6BrNO2. Iwuketshezi olungenambala ukuya kokuphuzi ngokukhanyayo, oluguquguqukayo ezingeni lokushisa elilingana negumbi. I-hygroscopic futhi iyancibilika kuzincibilikisi zemvelo njenge-ethanol ne-dichloromethane.
I-methyl-2-bromoisonicotinate isetshenziswa kakhulu njengama-catalysts kanye ne-intermediate ekuphenduleni kwe-organic synthesis. Ingasetshenziswa njengento ebalulekile yokusetshenziswa emkhakheni wemithi, izibulala-zinambuzane kanye nodayi.
Indlela yokulungiselela ye-methyl-2-bromoisonicotinate ngokuvamile itholakala ngokusabela i-2-bromopyridine nge-methyl formate. Izimo ezithile zokuhlola zingahluka, kodwa ngokuvamile, ukusabela kwenziwa ngaphansi kwezimo ze-alkaline, futhi izisekelo ezivame ukusetshenziswa yi-sodium hydroxide noma i-sodium carbonate.
Ngolwazi lwezokuphepha lwe-methyl-2-bromoisonicotinate, iyinhlanganisela ecasulayo negqwalayo. Ukuthinta isikhumba, amehlo, noma umgudu wokuphefumula kungabangela ukucasuka nokungakhululeki. Ngakho-ke, izinyathelo zokuphepha ezidingekayo kufanele zithathwe ngesikhathi sokusebenza, njengokugqoka amagilavu okuzivikela, izibuko kanye nemaski. Ngaphezu kwalokho, kufanele igcinwe esitsheni esivaliwe, kude nemithombo yomlilo kanye nezindawo zokushisa eziphakeme. Uma kwenzeka ingozi, shayela ngokushesha indawo ethintekile ngamanzi amaningi futhi ufune usizo lwezokwelapha ngesikhathi esifanele. Landela izinqubo zokuphepha ezifanele kanye nezincomo.
