5-Bromo-4-methyl-pyridine-2-carboxylic acid (CAS# 886365-02-2)
Intshayelelo
Yinto ephilayo i-organic compound ene-chemical formula yi-C7H6BrNO2.
Iipropati zekhompawundi ziquka:
-Imbonakalo: Ayinambala ukuya kwikristale etyheli okanye umgubo
-Indawo yokunyibilika: 63-66°C
-Indawo yokuBilisa: 250-252°C
-Ubuninzi: 1.65g/cm3
Ihlala isetyenziswa njengendawo ephakathi kwi-synthesis yezinye izinto eziphilayo. Inezicelo ezibalulekileyo kwicandelo lamayeza kwaye ingasetyenziselwa ukudibanisa iimveliso zeamolekyuli zamachiza athile. Ukongeza, ikwayi-synthetic intermediate ye-antibacterial agents esebenzayo kakhulu. Ezinye izinto ezinokuthi zisetyenziswe ziquka ukusetyenziswa njenge-catalysts, iidayi ze-photosensitizing, kunye nezibulali zinambuzane.
Indlela yokulungiselela i-pyridine ngokuyinhloko isekelwe kwi-bromination ye-4-methylpyridine kunye ne-sodium cyanide kwi-5-bromo-4-methylpyridine, kwaye emva koko iphendule nge-rhenium trioxide kwi-dichloromethane ukuvelisa imveliso ekujoliswe kuyo.
Malunga nolwazi lokhuseleko, lunobuthi obuthile kunye nokucaphuka. Nceda uqaphele le miba ilandelayo xa uyisebenzisa:
-Kuphephe ukuphefumla uthuli, umsi kunye neegesi ukuthintela ukudibana nolusu namehlo.
-Nxiba izixhobo ezifanelekileyo zokukhusela ngexesha lokusetyenziswa, njengeeglasi zokukhusela iikhemikhali, iiglavu zokukhusela kunye neemaski zokukhusela.
-Ifanele isetyenziswe kwindawo engena umoya kwaye igcine ucoceko kwindawo yokusebenza.
-Ukugcinwa kufuneka kugcinwe kwindawo eyomileyo, epholileyo, kude nomlilo kunye ne-oxidizing agents.
Xa usebenzisa isinyithi, nceda ulandele ukhuseleko olufanelekileyo kunye nemimiselo, kwaye uvavanye iingozi zayo kunye neengozi ezinokwenzeka ngokwemeko ethile.
