CAS: {16681-56-4 {2- bromo {} h-imidazole

{{0 {0}} Bromo {{1} h-imidazole qhov hnyav yog 147. 00. 2- bromo {{} h-imidazole yog cov tshuaj pleev ib ce, acetone thiab dimethyl sulfoxide (DMSO). Nws yuav tsum tau muab ntim thiab khaws cia rau ntawm 2-8 degree los tswj kev ruaj khov.

Siv:

Cov tshuaj nruab nrab: {{2- bromo {{h-imidirole tshuaj, tshuaj tiv thaiv tshuaj thiab anticazole derivatives).
Organic synthesis: raws li lub bromination reagent, nws koom rau hauv kev tsim kho ntawm heterocyclic tebchaw thiab yog siv nyob rau hauv kev npaj tshuaj tua kab, dyes thiab cov ntaub ntawv ua haujlwm.
Cov chaw tshawb fawb: Siv nyob rau hauv ligand tsim ntawm cov hlau sib hlau thiab catalytic cov kev tshawb fawb.

Txoj kev npaj:
Bromination: 1h-imidazole yog reacted nrog bromine, thiab cov tshuaj tiv thaiv yog catalyszed los ntawm kev ntxiv cov khoom siv roj ci los ntawm daim ntawv {2}} h-imidazole.
Bromination: 1h-imidazole yog reodine nrog sodium nitrite los ua nitrosoimidazole, thiab tom qab ntawd nws tau los ntawm bromination cov tshuaj tiv thaiv.

Gnee Chem yog kev nkag rau cov kev tshawb fawb, kev txhim kho, ntau lawm thiab muag ntawm lub xeev Henan, npog thaj tsam ntawm 3,600 square metres. Peb muaj tus kws tshaj lij, zoo-nruab nrog thiab cov pab pawg R & D muaj ntau dua 10 xyoo ntawm R & D kev paub. Peb cia siab tias tsim kev sib koom tes ntev thiab muaj kev sib koom tes sib koom tes nrog cov phooj ywg ntxiv yav tom ntej, thiab muab cov khoom lag luam thiab cov kev pabcuam zoo tshaj rau peb cov neeg siv khoom.
